Interpretation Introduction

Interpretation:

The molar solubility and solubility in $\text{g/L}$ units of each of the given salts at $25°\text{C}$ is to be calculated.

Concept introduction:

At a given temperature, the product of molar concentrations of the ions of 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, more 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 $\text{g/L}$ units is calculated by the expression:

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