      The water molecule is amphoteric in aqueous solution

      A water molecule in aqueous solution. How can you tell it’s being dissolved, or doing the dissolving?

        In high school I was told that one in avagadros number of water molecules splits into ions.
        Is that right? It seems like a very small amount.

          The dissociation constant of pure water at RT is 1x10^-14. This is many magnitudes more than just one per avogadros number. The “trick” is that any given molecule of water basically has that 1x10^-14 chance of being split or otherwise whole at any given time.
