Interpretation Introduction

Interpretation: The solubility product of $\text{Ce}{\left({\text{IO}}_{\text{3}}\right)}_{\text{3}}$ and concentration of each ion ${\text{Ce}}^{\text{3}+}$ and ${\text{IO}}_{\text{3}}{}^{\text{3}-}$ is given. It is to be checked that $\text{Ce}{\left({\text{IO}}_{\text{3}}\right)}_{\text{3}}$ will precipitate out or not when two solutions are mixed.

Concept introduction: The formation of solid in a solution is known as precipitation.

Solubility product, $K_{\text{sp}}$ is defined as the concentration of ions in a saturated solution where each ion is raised to the power of their coefficients. Ion product, $Q$ is defined as the initial concentration of ions in any solution where each ion is raised to the power of their coefficients.

The relation between ion product, $Q$ and solubility product, $K_{\text{sp}}$ is as follows.

• If $K_{\text{sp}}>Q$, then no precipitate will form.
• If $K_{\text{sp}}<Q$, then precipitate will form.
• If $K_{\text{sp}}=Q$, then the solution will be in just saturation.
