Question

A solution contains 0.10 M Sr(NO₃)₂ and 0.20 M Bi(NO₃)₃. When solid Na₃AsO₄ is added to the solution a precipitation forms. What is the maximum concentration of AsO₄³⁻ just before the first salt precipitates?

Ksp of Sr₃(AsO₄)₂ = 4.29 x 10⁻¹⁹ and BiAsO₄ = 4.43 x 10⁻¹⁰

Expert Solution

Step 1: Introduce question concept

The question is based on the concept of solubility product principle. It states that when a weak electrolyte is dissolved in water it partially dissociates. Only a small quantity of salt is dissolved and it quickly attains equilibrium and becomes saturated.
