Characteristics of Weak Polyprotic Acids
Since K
values for successive hydrogen ions are much smaller than the one before, the pH only depends on the
a
first ionization that can be assumed to be a monoprotic acid.
For sulfuric acid the K
values are so close that for large concentrations the second dissociation does not matter.

But, for small concentrations that second dissociation is very important.
