Question

What is the molar concentration of silver ion in a solution containing 1.3 × 10–4 M CrO42–, saturated with Ag2CrO4?
The Solubility Product Constant, Ksp for Ag2CrO4 is 9 × 10–12


(A) 1.3 × 10–16
(B) 7 × 10–16
(C) 9 × 10–12
(D) 2.6 × 10–4
(E) 7 × 10–3

Answer 1

This is a common ion worked the same way as the BaSO4 and Na2SO4 problem.

Answer 2

1.3x10^-4 is the answer to the question.
