What is the ratio of degree of dissociation () when a acetic acid solution is diluted to ? — Ionic Equilibrium Chemistry Question
Question
What is the ratio of degree of dissociation ($\alpha$) when a $1 \text{ M }$ acetic acid solution is diluted to $1/10 \text{ M }$?
Answer: B
💡 Solution & Explanation
Ostwald's Law: $\alpha \propto 1/\sqrt{C}$. Thus, $\alpha_1 / \alpha_2 = \sqrt{C_2 / C_1} = \sqrt{0.1 / 1} = \sqrt{1/10} \approx 1/3.16$.
