Duncan,

Once a compounds dissolve, they do dissociate, so I am uncertain of the
point of your comment about them.


Umm, that's not quite true is it? For example, sugar (e.g. sucrose)
dissolves but doesn't dissociate. Sucrose will hydrolize but that's a
separate reaction from dissolution and requires a catalyst/enzyme or
heating for any significant hydrolysis to take place. Although in the
vast majority of cases compounds do dissociate when they dissolve the
point is that it is not true that dissolution = dissociation. While
not very relevant to the discussion his point is valid.
