Chapter 15, Problem 60E

Interpretation Introduction

Interpretation:

The equilibrium concentration of ${\left[\text{Al}{\left({\text{H}}_2\text{O}\right)}_6\right]}^{3+}$ is to be calculated.

Concept Introduction:

The equilibrium constant is the ratio of concentrations of products to that of reactants each raised to the power of their respective stoichiometric coefficients.

For a chemical reaction:

$\text{aA}+\text{bB}\rightleftharpoons \text{cC}+\text{dD}$.

The equilibrium expression can be written as:

$K_{\text{eq}}=\frac{{\left[\text{C}\right]}^c{\left[\text{D}\right]}^d}{{\left[\text{A}\right]}^a{\left[\text{B}\right]}^b}$

Here, $\left[\text{C}\right]$, $\left[\text{D}\right]$ are a concentration of products and $\left[\text{A}\right]$, $\left[\text{B}\right]$ are a concentration of reactants,

and $a,b,c,andd$ are stoichiometric coefficients.

The solubility product $\left(K_{\text{sp}}\right)$ value measures the solubility of salt dissolved in the solvent at a given temperature.
