Chemistry Sets for Adults?

An Anonymous Coward asks "I've been pursuing a few different lines of study, to refresh myself in basic sciences before I return to school. Right now I am reading up on Chemistry, and thought it would be fun to acquire a chemistry set just to play around with and maybe learn a few things from. Do any science geeks here have any suggestions?" My childhood garage probably still has purple and black stains all over it (lucky I was wearing glasses). 300 in one electronics kits, anyone?

      Doing actual experiments is important for chemistry in particular because otherwise learning the nomenclature is next to impossible. This is not the case as much for intro physics.

      When I was learning all that stuff, we had all these tables with the IUPAC naming conventions and such, and none of it really connected togething into something coherent. But once you actually get working with a dozen chemicals at once, you have to catalogue your results some how and then the real relationships between anions, cations, acids, bases, etc are made clear to you. It's even better if you to chemistry experiments with a friend helping. (Joke not intended ;-) You have to coordinate your plans and communicate results to each other.

      I know from experience that it is at least 10X easier to learn chemistry in terms of the nomenclature, methods, and overall properties of different structures by lab work than by reading.

      And it works. It's been two years since I've had to take a chemistry course and I still know all my common anions (formula, charge, name) including the names for versions with up to one extra or two less oxygens off my heart.

      Exactly - that was the experience I had with my old 300-in-1 chemistry set about 27 years ago.

      I did 30 pages of book/guided stuff. E.g. filtering a sand and salt solution, then spending 2 hours getting the salt out of the solution... at the end, guess what? I had salt again!!! Gee, that was fun.

      I switched to my own guided experiments soon after that: KnO3 is cool, magnesium burns pretty well, sulfur smells bad, but hydrogen sulphide is even better! My father (a chemist) banished my experiments to the garage.

      Next month, I told my parents I needed a pound of sodium chlorate as a desiccant. My father managed to keep a straight face, but bought it for me anyway.

      Many more self-directed experiments were performed, and I found myself learning in leaps and bounds: I learned about the surface area of reactants when I thoughtlessly substituted powdered charcoal for granulated sugar in a simple propulsion experiment. Haha, skin and hair grow back.

      As I've stated before, I used to work in a secondary lead refinery. There were massive air filtration units to remove part of the lead dust from the air - we still had to wear respirators - and collect it in large canvas bags that were repeatedly shaken by the collection equipment to get the dust to fall to the bottom of the bags.

      The dust collected in these bags was very fine (large lead particles don't traditionally remain airborne for very long at 1G). Fine metallic dusts are highly flammable when mixed with an oxidant.

      One of the methods we used for determining various elemental levels was to combine a fixed amount of a sample with an equal amount of Sodium Peroxide (which is a highly reactive oxidizer), heat the sample mixture until it became molten and then drop the crucible full of molten reactive material into a beaker containing a fixed amount of de-ionized water. After the rapid reaction of the very hot oxidizer coming into contact with the water, we would fish out the crucible and run the water through an atomic adsorption spectrophotometer which would tell us how much of which element were present. In addition to being a very cool reaction to watch, it would take almost any material and convert it into a water soluble salt so it could be read on the spec.

      Because of the reactivity of Sodium Peroxide (which all by itself will burst into flames when mixed with water) we would only use this method on material that was traditionally non-flammable such as the slag from the various furnaces.

      The person who was promoted to lab manager when the original manager left was not a chemist, and had never taken a chemistry class in his life and didn't understand the basic rules of chemistry (i.e., hot glassware looks exactly the same as cold glassware) and was often times caught doing something stupid.

      One day when the floor supervisor brought in a sample of lead dust from the shaker bags to be tested, Tom (the new manager) got a hold of the sample and volunteered to do the analysis. I watched him weigh out equal amounts of dust and Sodium Peroxide, but before he could combine them in the zirconium crucible I pointed out to him that you really shouldn't mix highly flammable materials with a highly reactive oxidizer.

      He politely told me to mind my own business and that he was the lab manager and he knew what he was doing. I then proceeded to move quickly away from him and watched carefully from across the lab as he not only proceeded to mix the two materials together (luckily without incident) but then proceeded to pick up a pestle and try to grind the two materials together in the crucible.

      For those who have never worked with potentially explosive materials, they can be set off by a variety of sources including, but not limited to, heat, pressure and shock. When you combine two reactive materials in a metal crucible and then proceed to grind them together with a heavy porcelain pestle, you introduce heat, pressure and shock. Needless to say within about two seconds the materials combined together in a very impressively large flash, severely burning the hand holding the pestle and burning off just the upper part of his eyebrows that extended beyond the top of his safety glasses.

      Nitroglycerin Recipe by the Jolly Roger
      Like all chemists I must advise you all to take the greatest care and caution when you are doing this. Even if you have made this stuff before.
      This first article will give you information on making nitroglyerin, the basic ingredient in a lot of explosives such as straight dynamites, and geletin dynamites.

      Making nitroglycerin

      1. Fill a 75-milliliter beaker to the 13 ml. Level with fuming red nitric acid, of 98% pure concentration.
      2. Place the beaker in an ice bath and allow to cool below room temp.
      3. After it has cooled, add to it three times the amount of fuming sulferic acid (99% h2so4). In other words, add to the now-cool fuming nitric acid 39 ml. Of fuming sulferic acid. When mixing any acids, always do it slowly and carefully to avoid splattering.
      4. When the two are mixed, lower thier temp. By adding more ice to the bath, about 10-15 degrees centigrade. (Use a mercury-operated thermometer)
      5. When the acid solution has cooled to the desired temperature, it is ready for the glycerin. The glycerin must be added in small amounts using a medicine dropper. (Read this step about 10 times!) Glycerin is added slowly and carefully (i mean careful!) Until the entire surface of the acid it covered with it.
      6. This is a dangerous point since the nitration will take place as soon as the glycerin is added. The nitration will produce heat, so the solution must be kept below 30 degrees centigrade! If the solution should go above 30 degrees, immediately dump the solution into the ice bath! This will insure that it does not go off in your face!
      7. For the first ten minutes of nitration, the mixture should be gently stirred. In a normal reaction the nitroglycerin will form as a layer on top of the acid solution, while the sulferic acid will absorb the excess water.
      8. After the nitration has taken place, and the nitroglycerin has formed on the top of the solution, the entire beaker should be transferred slowly and carefully to another beaker of water. When this is done the nitroglycerin will settle at the bottem so the other acids can be drained away.
      9. After removing as much acid as posible without disturbing the nitroglycerin, remove the nitroglycerin with an eyedropper and place it in a bicarbonate of soda (sodium bicarbonate in case you didn't know) solution. The sodium is an alkalai and will nuetralize much of the acid remaining. This process should be repeated as much as necesarry using blue litmus paper to check for the presence of acid. The remaining acid only makes the nitroglycerin more unstable than it already is.
      10. Finally! The final step is to remove the nitroglycerin from the bicarbonate. His is done with and eye- dropper, slowly and carefully. The usual test to see if nitration has been successful is to place one drop of the nitroglycerin on metal and ignite it. If it is true nitroglycerin it will burn with a clear blue flame.

Therefore my original statement:

      Buying hummus and charcoal can get the suits at your door...

      I totally agree with this. Most "modern" chemistry sets are so sickeningly-safe that they do not truly allow any chemistry to be done. I would collect your own chemicals, maybe buying a chemistry set to give you some guidance.

      There are several cautions that I would keep in mind. First of all, chemistry is highly dangerous. Many of the "first" discoverers of a chemical compound of process have actually turned out to be the second, third, etc. The true first discoverers literally killed themselves in the attempt and were thus not able to make their claim to fame! The first inventor of gunpowder, the first discoverer of fluorine, chemistry is riddled with those that tried something without understanding the consequences of their actions.

      Get several good chemistry texts and read them all the way through. Start off with simple, harmless experiments. Do not try anything potentially explosive, corrosive, or vapor-producing. Keep several neutralizing agents on hand, such as baking soda, lime, sand, a good multi-purpose fire extinguisher. Perform your experiments in an extremely well-ventilated area that has been fireproofed and is far away from any living or eating areas. A separate shack is a good place. Use goggles, a heavy rubberized and/or canvas smock, solid leather shoes, disposable gloves and face masks for some experiments.

      Never leave an experiment unattended. Never dump the results of your experiments in the same place, they can sometimes cross-react and form a dangerous mixture. Do not store anything which has the potential to become unstable, many nitrogen and phosphorous compounds can spontaneously react and cause extreme heat, vapors, or explosions.

      Make sure of the purity of your ingredients. If you get ordinary bleach for the sodium hypoclorite be careful - perfumes, surfactants, and other agents are often added to them which can cause unwanted reactions to occur. The same goes for household ammonia cleaning solutions. Most metals you will get will be alloys, always understand the elements in the alloy and how they may react in an experiment.

      Yeah, it's a lot to keep in mind, but chemistry is truly a dangerous business. I've been working in chemical labs for over 10 years and I've seen professional chemists with doctorates have accidents that you wouldn't believe. Explosions, runaway reactions, improperly ventilated experiments, splashes of highly corrosive compounds, forgetting to turn on or off some crucial bit of equipment, a lot of people get hurt even in the safest laboratory. I'm very careful simply because every exposure to some of these chemicals shortens my life-span. Many of the chemicals will take up permanent residence in your bones, will leave holes in your liver, will cause you to go blind, or even will make you go sterile. Lots of them have a cumulative effect so every exposure increases the risk, no matter how much time has passed.

Thus, we have to use approximations that in the end may require as much creativity as the physics itself.

It was written during the Vietnam era by a pissed-off draft age guy. Now he's turned to Jesus and says he wishes he hadn't written the book at all. Another mind lost to religion.

    The best explosive recipe in the book is one that the author discounts in passing- nitrogen triiodide, or NI3. (Actually, the structure is NI3-NH3, where the NH3 is bound to the NI3 electrostatically by what resemble hydrogen bonds.) According to the Cookbook a fly landing on it will set it off (which is probably true, although I never succeeded in getting a fly to cooperate). It claims it's too useless for any serious consideration when planning your anarchy. It might not be good for that, but it's great for pranks. I've had so much fun with that stuff. The secret to NI3 is DO NOT MAKE TOO MUCH OF IT. That way you can keep your fingers. A gram is way too much. Just take a few iodine crystals and put them under ammonia, and presto, it turns into this black powder. If you keep it under the ammonia, it's actually quite stable. When not under ammonia (even when under pure water) it might go off at any moment. Pick it up from the ammonia with a plastic eyedropper, and deposit the black sludge on some surface. Once dry it rapidly loses its NH3 adduct and becomes extremely sensitive to shock, decomposing explosively producing N2 and I2. Don't get traces of it on your clothes or skin, or you'll be treated to a continuous snap-crackle-pop of microscopic explosions (quite annoying).

    Finding references on it is difficult- it's almost like people don't want to do research on it. It's probably unstable because the iodine atoms are huge compared to the nitrogen. Congestion around the central N forces the molecule into a planar shape, with repulsive interactions among the three iodines, so it's unhappy for steric reasons. One thing I did find out was that the stuff turns bright orange if you leave it under the ammonia for a long time (like a month). This is probably because it picks up additional NH3 adducts.

      Then transfer the wet precipitate to a suitable container preferably made from soft plastic that is alcohol-resistant and with a soft plastic lid with an easily-cleaned screwtop.

      Fill the container TO THE BRIM with alcohol.

      Ensure that the screw threads and cap are completely free of precipitate and that the wet precipitate is then COMPLETELY COVERED.

      In this state the compound appears to be quite stable over long periods of time. It will dry out very quickly when placed on a surface and then become extremely sensitive to vibration etc.

      PS: on the topic of explosives, those who fool with chlorate compounds be aware that many have died or been seriously maimed by contaminating screw threads with powder and then when the thread is tightened or loosened, detonation occurs by friction.

      Bear in mind also that ignition due to static discharge has been known to happen.

As it turns out, some of these constructs has proven themselves useful in science, but that doesn't make math itself a science. Neither is logic a science. Nobody does experiments in either math or logic.

    As for whether the rest of the argument is true, depends on your own sillyness. Biology is no more applied chemistry than enjoying dinner is applied thermodynamics. While it is true that microbiologists worry a lot about chemistry, there are also other biologists who couldn't care less, and work with entirely other things.

    In the same vein, one could argue for the same hierarchy in computer scientists/engineers. At the top, we have the hardware engineers, then microcode developers, people who write device-drivers, etc, system-level programmers, application-level programmers, scripters, and end-users.

    In reality, the tasks that end-users perform at a computer needs be no more easy than what hardware-engineers do when constructing one (and in doing that, most hardware engineers are also end-users...). The only difference is that it requires a different kind of knowledge.

    While it is true that physics concerns itself more with "fundamental principles" than chemistry, and logic is more "fundamental" than math, this does in no way imply that math is worthless because logic is more "fundamental", or that people should stop studying chemistry, because physics is more "fundamental".

    We cannot, and probably never will, be able to easily and automatically derive all important principles of math from logic, all of chemistry from physics, all of biology from chemistry, all of medicine from biology, all of psychology from medicine, all of social science from psychology, and so on. The value of science is not in it's "fundamentalness". It's in its usefulness (either direct usefullness for applied science, or in it's potential for understanding nature better in the long term for pure science).

    First of all I would reccomend that you not do any home experiments unless:
    a.) you are fully aware of the hazards/risks involved and know how to minimize them.
    or
    b.) the experiments you perform are not hazardous.

    Check up on your laboratory safety at The Laboratory Safety Institute or take an Online Safety Course or visit OSHA's site. Final note on safety---> It's always fun until someone gets hurt!!!

    I assume that you still want to do chemistry experiments. Choose choice b. There are many experiments that you can do that are not hazardous to humans. e. g. mix Baking Soda an Vinegar to produce carbon dioxide.

    Keeping a laboratory book is essential in science laboratory and highly reccommended for amature experementation. This typically includes information such as Introduction/Purpose(what do you expect to occur)...Experimental Method(how you will do the experiment, EXACTLY)....Experimental Results...Disscussion of Experimental Results/Conclusion...Reference information.

    Basically as far as the laboratory manual is concerned, your experiments should be repeatable by someone else. An excellent book on the subject is : H. M. Kanare, Writing the Laboratory Notebook, American Chemical Society, Washington, D. C., 1985; ASIN: 0841209065.

    You should gain an understanding of some general laboratory techniques. e. g. measuring liquids, determining mass, quantatively transfering liquids, pipeting, using a buret. Technique is very important in Experimental Chemistry. Do not, however, underestimate the importants of theory. Also chemistry and science in general is about gathering and analyzing data. Therefore it is essential that you understand how to visually present you data (e. i. make a data table and graph). A good book on this subject is : Edward R. Tuft's 'The Visual Display of Quantative Information', Graphic Press, Cheshire CT, 1983.

    As far as studying general chemistry goes; I would recommend you get a handle on fundamental chemical laws, basic naming of chemical compounds, understand the polyatomic ions, stoichiometry (e.g. 2 moles of hydrogen react with one mole of oxygen to produce 1 mole of water), Acid-Base Reactions, Oxidation-Reduction Reactions, gas laws and thermochemistry.

    These are the things that you should master in the first course of general inorganic chemistry.

    As far as amateur science is concerned the Society for Amature Scientists is excellent.

    I think chemistry as an amature science is greatly underrepresented. As far as chemistry sets are concerned they are generally geared toward children and therefore may not be much fun for an adult. If you study chemistry seriously, and are interested, you can develop you own experiments. As far as chemicals and glassware are concened; it's probably better to get them at a yard sale or auction site. This is because they are cheaper. If you don't know exactly what chemical you need it is not recommended that you buy any though. Some chemicals available on ebay are extremely hazardous.

    For further information I would recommend the very excellent Jounal of Chemical Education.
