Chapter 18, Problem 5E

Interpretation Introduction

Interpretation:

The molar solubility of the given molecules should be arranged in increasing order.

Concept introduction:

Solubility product constant $\left(K_{\text{sp}}\right)$ is also an equilibrium constant and it is calculated as the product of the equilibrium concentration of the ions present in the salt raised to the power of their coefficients respectively in the balanced chemical equation.

For a general salt ${\text{A}}_{\text{x}}{\text{B}}_{\text{y}}$, the balanced chemical reaction for its equilibrium is given as,

${\text{A}}_x{\text{B}}_y\left(s\right)\rightleftharpoons x{\text{A}}^{y+}\left(aq\right)+y{\text{B}}^{-x}\left(aq\right)$

The expression of the solubility product is written as follows:

$K_{\text{sp}}={\left[{\text{A}}^{y+}\right]}^x{\left[{\text{B}}^{-x}\right]}^y$
