Chapter 15, Problem 54E

Interpretation Introduction

Interpretation: The concentration and volume of ${\text{K}}_{\text{2}}{\text{SO}}_{\text{4}},{\text{BaCl}}_{\text{2}}$ is given. The final concentration of barium ${\text{Ba}}^{\text{2}+}\left(aq\right)$ and sulfate ${\text{SO}}_{\text{4}}{}^{\text{2}-}\left(aq\right)$ is to be calculated.

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.
