Chapter 15, Problem 95QRT

Interpretation Introduction

Interpretation:

If more solid $\text{AgCl}$ is added to a solution saturated with ${\text{Ag}}^{+}$ and ${\text{Cl}}^{-}$ ions, then the effect on equilibrium has to be stated.

Concept Introduction:

The term $Q_{\text{sp}}$ is known as the ionic product and $K_{\text{sp}}$ is known as the solubility product.  Both the terms relate the ions present in a solution on the basis of the product of their concentrations in the solution.  The difference lies in the fact that solubility product is used when there is an equilibrium relationship between the unionized salt and its ions.
