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.
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?
