A Water Molecule's Chemical Formula Isn't Really H20

hackwrench writes "According to this article in Physics News Update, a water molecule's chemical formula is really not H2O, at least from the perspective of neutrons and electrons interacting with the molecule for only attoseconds (less than 10-15 seconds). According to new and recent experiments, neutrons and electrons colliding with water for just attoseconds will see a ratio of hydrogen to oxygen of roughly 1.5 to 1, so a more accurate formula for water under these circumstances would be H1.5O."

  23. More than elementary chemistry by xenocide2 · · Score: 1

    Your second grade teacher may have taught you that water is H20, but she neglected to mention that water is in an equilbrium between H20 and H + OH. Its typically thought that the coefficient of seperation of water is pretty insigifnicant, along the lines of 10^-14.

    Meaning that if the water has a pH of 7 then we should be expecting something closer H1.999O. If the difference is flawed experimentation, I would expect proper scientific reserarch to explain this, just as I'd expect it to explain the reasons that even the rudimentary equalibrium analysis is wrong for the timeframe of a attosecend.

      No, we should expect to find a mix of H2O, H, and OH. In any macroscopic volume the ratio between H & O should be 2, not 1.999 or even 1.9999999. The pH shouldn't even enter into it (if the H+'s collectively wandered a macroscopic distance from the OH-'s, water would be incredibly dangerous).

      Remember, they were looking at the H's & O's via p + n & p + e scattering.

    If you would have RTFA before posting, you would know that they aren't saying that at all.
    While the exact details are still being debated by theorists, the researchers' own theoretical considerations suggest the presence of short-lived (sub-femtosecond) entanglement, in which protons in adjacent hydrogen atoms (and possibly the surrounding electrons) are all interlinked in such a way as to change the nature of the scattering results. Realizing that water itself has anomalous properties, the researchers repeated the neutron experiments in other more typical molecules, for instance in benzene (conventionally noted as C6H6). In that case, they found that the neutrons saw a ratio of hydrogen to carbon of 4.5 to 6! Meanwhile, this effect was also confirmed in various hydrogen-containing metals, in a collaboration with Uppsala University in Sweden.
    They are saying that maybe at attosecond time scales, maybe the adjacent hydrogen nuclei are entangled in such a way that fewer of them interact with the incoming particle, or something to that effect. To fully understand this probably requires a deeper knowlege of quantum mechanics and more detail than this article provides, but it is not without precident for many particles to behave as one. Check out Bose-Einstein condensates for info on that.

      No, the editing/summary of the paper isn't very good. The thing is, one expects to the contributions of the scattering of the individual atoms to sum linearly at the energies used. An analogy might be that you found a compound that was more or less radioactive than expected from the proportion of it's constituent elements. Chemistry shouldn't affect nuclear interactions like that.

      Won't affect the textbooks, don't worry!!

      It will, if there is anything in it, because the published results are extremely surprising. They just may not be the chemistry ones.

  37. Difference btw. molecules and compounds by meridoc · · Score: 1

    Chemically speaking...

    A molecule is something with a molecular formula, made up of a specific number of atoms (i.e., integer numbers). It also has a particular shape and its bonds are arranged in a particular way. Change one atom or one bond and you change the molecule and its properties.

    A compound (like some of the zeolites and semiconductors others have mentioned) is a mix of bonded atoms that, on average have a formula that may contain fractions or decimals. Because this is an average, the compound has no distinct start or end, and if one atom is removed the average still probably holds.

    Because water is a molecule (even though its ions are common), its formula will always be H2O... to a chemist.
