Question

Use the following information to answer H 2 Se: K a1 = 1.0 x 10 -4 , K a2 = 1.0 x 10 -10 -The base-ionization constant for the Se^2- ion would be:

Quizplus · Accepted Answer

The base-ionization constant Kb1 for Se^2- is calculated using the relation Kb1 = Kw/Ka2, where Kw is the ion-product constant of water (1.0 x 10^-14). Given Ka2 = 1.0 x 10^-10, Kb1 = 1.0 x 10^-14 / 1.0 x 10^-10 = 1.0 x 10^-4.
