Interpretation Introduction

Interpretation:

The effect of reaction, ${\text{CO}}_3^{2-}\left(\text{aq}\right)+{\text{H}}_{\text{2}}\text{O}\left(l\right)\rightleftharpoons {\text{HCO}}_3^{-}\left(\text{aq}\right)+{\text{OH}}^{-}\left(\text{aq}\right)$ on the solubility of ${\text{CaCO}}_{\text{3}}$ has to be stated by the use of Le Chatelier’s Principle.

Concept Introduction:

The equilibrium state of a chemical reaction is the state at which the rate of reaction going into the forward direction becomes equal to the rate of reaction going into the backward direction.  The general equilibrium reaction is shown below.

$a\text{A}+b\text{B}\rightleftharpoons c\text{C}+d\text{D}$

According to Le Chatelier’s Principle, “after any change in the reaction system, the equilibrium shifts in such a way or a direction that it can minimize the effects of change”.
