For weak electrolyte, AB, the degree of ionization would be () — Ionic Equilibrium Chemistry Question

💡 Solution & Explanation

According to Ostwald's dilution law for a weak electrolyte, the degree of ionization is $\alpha = \sqrt{\frac{K}{C}}$. The concentration $C$ is defined as moles/volume. Since there is exactly 1 mole of the electrolyte, $C = \frac{1}{V}$. Substituting this into the formula gives $\alpha = \sqrt{K \cdot V}$.
