What did suprise me was that although a number of papers tend to suggest that the SO2.hydrate is actually the sulfurous acid itself, nobody has
mentioned this phase-forming behaviour when discussing this article. Despite the fact that the acidity of the solution is now pretty much what I
expected, it appears that my inability to read japanese script has led to a seriously confusing reaction
...
PS I'd have to agree not_important, but I am still stumped how the crystal ghosts continue to exist even when the solution is thawed and vigorously
stirred. The only thing I can think of is that the putative H2SO3 is the clathrate forming compound - perhaps the other SO2 in the solution is simply
dissolved... Alternatively, perhaps the SO2.H2O clathrate is an intermediate between the H2SO3 and the H2SO4 formed by the dissolved oxygen? Does
anybody actually 'KNOW'?
