Give the expression for the solubility product constant for pbcl2.

when the salt PbCl ₂ is dissolved it dissociates as follows;

PbCl ₂ - - - > Pb ²⁺ + 2Cl ⁻

solubility product constant written as ksp is the equilibirum constant for a solid that dissolves in water.

the expression for ksp is; ksp = [Pb ²⁺ ][Cl ⁻ ] ²
