Sulfuric acid (H2SO4) accounts for as much as 80 percent of the acid in acid rain. Its first ionization is complete, producing H+ and the hydrogen sulfate ion:

Its second ionization, which produces additional H+ and the sulfate ion, has an ionization constant  of 1.3 × 10−2.

Calculate the concentration of all species in a raindrop in which the sulfuric acid concentration is 4.00 × 10−5 M. Assume that sulfuric acid is the only acid present.
