Chapter 16, Problem 16.111QP

Ionization of the first proton from H₂SO₄ is complete (H₂SO₄ is a strong acid); the acid-ionization constant for the second proton is 1.1 × 10⁻². a What would be the approximate hydronium-ion concentration in 0.100 M H₂SO₄ if ionization of the second proton were ignored? b The ionization of the second proton must be considered for a more exact answer, however. Calculate the hydronium-ion concentration in 0.100 M H₂SO₄, accounting for the ionization of both protons.
