Chapter 17, Problem 68RQ

Interpretation Introduction

Interpretation: For the solution of $22.0\text{ mL}$ of $\text{0}\text{.100M}$ ${\text{AgNO}}_3$ with $45.0\text{ mL}$ of $\text{0}\text{.0260M}$ ${\text{NaC}}_{\text{2}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}$, the formation of precipitate is to be predicted.

Concept Introduction:

The formation of precipitate can be predicted from the concentrations of the ions of a salt in a solution and the value of $K_{\text{sp}}$ for the salt. For the precipitation of a salt, the solution must be supersaturated. The value of $Q$, the ion product, indicates the saturation or unsaturation of the solution.

If $Q>K_{\text{sp}}$, then the solution is supersaturated and precipitate will be formed.
