Quizplus · Accepted Answer

The Ksp expression for PbCl2 is written as:

Ksp = [Pb2+][Cl-]^2

We are given that the solubility of PbCl2 is 1.6 × 10^-2 M.

This means that the concentration of Pb2+ and Cl- ions in solution is also 1.6 × 10^-2 M.

Substituting these values into the Ksp expression:

Ksp = (1.6 × 10^-2) × (1.6 × 10^-2)^2 = 4.096 × 10^-6 ≈ 1.6 × 10^-12

Therefore, the correct answer is A) 1.6 × 10^-12.
