Chapter 16, Problem 10CE

Interpretation Introduction

(a)

Interpretation:

The effect of adding $\text{Ca}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}$ in the chemical equilibrium, ${\text{CaCO}}_{\text{3}}\left(s\right)\rightleftharpoons {\text{Ca}}^{2+}\left(aq\right)+{\text{CO}}_{\text{3}}{}^{2-}\left(aq\right)$ 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. Increase in concentration of any species, shifts the equilibrium in a direction to counteract the change.

Interpretation Introduction

(b)

Interpretation:

The effect of adding ${\text{Na}}_{\text{2}}{\text{CO}}_{\text{3}}$ in the chemical equilibrium, ${\text{CaCO}}_{\text{3}}\left(s\right)\rightleftharpoons {\text{Ca}}^{2+}\left(aq\right)+{\text{CO}}_{\text{3}}{}^{2-}\left(aq\right)$ is to be stated.
