Are you familiar with what a buffer is?

anonymous · Answer

I think that the pH would not change. There is a big difference between the concentration of the acid, and the pH of the acid. Adding water would make an acid more dilute, and hence alter its concentration..., whereas the pH would remain the same...for example the pH of H2SO4 is always 0....no matter how concentrated or dilute it is.

It's possible for sulphuric acid to have a pH of 1. 
I don't think fuming sulphuric acid would even have a pH since it would completely dissociate.
