Chapter 15, Problem 90E

Interpretation Introduction

Interpretation: The equilibrium constant value, concentration of cation and concentration of anion are to be calculated.

Concept Introduction: Equilibrium constant $\left(K_{\text{eq}}\right)$ for a reaction can be defined as the ratio of the concentration of product to the concentration of reactant.

$K_{\text{eq}}=\frac{\left[\text{Product}\right]}{\left[\text{Reactant}\right]}$

Equilibrium constant is the dimensionless quantity.

The concentration has unit of moles per liter.
