Question

Which of the following factors will lead to an increase in the degree of ionization ($\alpha$) of a weak electrolyte in an aqueous solution?

Answer: A,D

💡 Solution & Explanation

The ionization process is endothermic, so increasing temperature shifts equilibrium forward, increasing $\alpha$. A higher dielectric constant increases the ionizing power of the solvent, separating ions more effectively. Concentration decreases $\alpha$ (by Ostwald's law $\alpha \propto 1/\sqrt{C}$), and a common ion suppresses ionization.
