Interpretation Introduction

Interpretation:

The solubility product constant $K_{sp}$ of the given salt solutions are to be calculated.

Concept introduction:

At a given temperature, the product ofmolar concentrations of the ions of a salt present in the solution is known as the solubility product of the salt. It is represented by $K_{sp}$.

Higher is the value of solubility product of a salt, higher is its solubility.

The presence of common ions in the solution decreases the solubility of a given compound.

For a general reaction: $\text{AB}\left(s\right)\rightleftharpoons {\text{A}}^{+}\left(aq\right)+{\text{B}}^{-}\left(aq\right)$

The solubility product can be calculated by the expression as: $K_{\text{sp}}{\text{= [A}}^{\text{+}}{\text{][B}}^{-}\text{]}$

Here, $K_{\text{sp}}$ is the solubility product constant and $sp$ stands for solubility product.

The solubility of compound in $\text{M}$ units is calculated by the expression:

$\text{solubility}\text{in}\text{M}=\frac{\text{solubility}\text{in g/L}}{\text{molar}\text{mass}}$
