Using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 pb+2(aq) + 2cl -(aq). if the value of ksp was determined to be only 1.2 x 10-2: too much solid has dissolved. additional precipitate is forming. the solution is unsaturated. the ions are now combining to reduce their concentrations.

The ions are now combining to reduce their concentrations.

Explanation:

PbCl₂(s) ⇄ Pb²⁺(aq) + 2Cl⁻(aq),

It is mentioned that the value of Ksp is 1.8 × 10⁻².

∵ The solubility product is lower for this reaction that means the ions produced are getting combined.

∴ Resulting in reducing the concentration of the ions and increasing the formation of the solid lead chloride.
