Interpretation Introduction

Interpretation:

The color representation has to be identified for the ${\text{base C}}^{\text{-}}{\text{ and the base D}}^{\text{-}}$ and the value of $\text{Kc > 1}$ or $\left(\text{Kc < 1}\right)$ has to be determined when the reaction between $\text{ HC}{\text{and D}}^{\text{-}}$.

Concept introduction:

In acid – base reaction, if the stronger acid produces the weaker acid which tells that the reaction favors the products, and the $\text{Kc}$ value is greater than one $\left(\text{Kc > 1}\right)$. If the weaker acid produces the stronger acid which tells that the reaction favors the reactants, and the $\text{Kc}$ value is less than one $\left(\text{Kc < 1}\right)$.
