Let's consider that sulfuric acid is very strong, and losing its first proton is very easy. Thus, let's assume we are left worrying about
where
Let's "calculate"
and work this in to our second proton dissociation calculation,
Hence, the pH of our solution is approximately,
which is reasonable because sulfuric acid is a very strong acid.
