Interpretation Introduction

Interpretation:

The value of ${\text{K}}_{\text{a}}$ of ${\text{C}}_{10}{\text{H}}_{14}{\text{N}}_2{\text{H}}^{\text{+}}$ and ${\text{C}}_{10}{\text{H}}_{14}{\text{N}}_2{\text{H}}_2{}^{\text{+}}$ that is the conjugate acids formed from nicotine by accepting two protons should be determined.

Concept introduction:

The acid-dissociation constant is the equilibrium constant of the dissociation reaction of an acid and it is denoted by ${\text{K}}_{\text{a}}$ .The equilibrium constant is quantitative measure of the acid strength in the solution.
