Sulfurous acid (H₂SO₃) is an acid and the sulfite ion (SO₃^2-) is a base. Which equation correctly describes the relationship between the equilibrium constants for these compounds?

Question

Quizplus · Accepted Answer

The relationship between the acid dissociation constant (Ka) of an acid and the base dissociation constant (Kb) of its conjugate base is given by Ka x Kb = Kw, where Kw is the ion product of water. Here, Ka1 is for H2SO3 and Kb2 is for SO3^2-.
