Interpretation Introduction

Interpretation:

The equilibrium constant expression for the reaction, ${\text{H}}_{\text{3}}{\text{PO}}_{\text{4}}\left(aq\right)\rightleftharpoons {\text{H}}^{\text{+}}\left(aq\right)+{\text{H}}_{\text{2}}{\text{PO}}_{\text{4}}{}^{-}\left(aq\right)$ is to be stated.

Concept introduction:

Equilibrium constant is a constant at any point of equilibrium; where, the ratio of the concentration of the products, each raised to power of their respective coefficient, to the concentration of the reactants, each raised to a power of their respective coefficient. Equilibrium of a weak acid lies on the left side of the equilibrium reaction.
