The ions are now combining to reduce their concentrations.

Explanation:

For the chemical equation:

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.

So, The ions are now combining to reduce their concentrations.
