Problem: What is the solubility (in M) of PbCl 2 in a 0.15 M solution of HCl? The Ksp of PbCl 2 is 1.6 × 10-5?

FREE Expert Solution

We have to determine the solubility of PbCl2 in a 0.15 M HCl solution.

PbCl2 is a sparingly soluble salt which partially dissociates in water to produce Pb2+ and Cl- ions.

PbCl2(s)  Pb2+(aq) + 2 Cl-(aq)

We can write the Ksp expression for this equilibrium.

Ksp = ProductsReactants = Pb2+Cl-2PbCl2 = Pb2+Cl-2
