Chapter 15, Problem 86E

Interpretation Introduction

Interpretation:

Molar solubility of $\text{PbS}$ salt to be determined.

Concept Introduction:

Molar solubility can be defined as the number of moles dissolved per liter of solution.

The unit of molar solubility is $\text{M}$ or $\frac{\text{mol}}{\text{liter}}$.

Molar solubility of salt is equal to the concentration of either ion if the same number of positive and negative ion obtained from the salt.

The solubility of salt depends upon their solubility product $\left({\text{K}}_{\text{sp}}\right)$ value.

For the given chemical equation $\text{A + B }\to \text{ C +}\text{}\text{D}$, the solubility product is given by ${\text{K}}_{\text{sp}}\text{ = }\left[\text{C}\right]\left[\text{D}\right]$.
