For two weak monobasic acids and to form isohydric solutions when dissolved in the same solvent, whi — Ionic Equilibrium Chemistry Question

💡 Solution & Explanation

Isohydric solutions have exactly the same $[H^+]$. For weak acids, $[H^+] = \sqrt{K_a C}$. Equating them gives $\sqrt{K_{a1}C_1} = \sqrt{K_{a2}C_2}$, which squares to the condition $K_{a1}C_1 = K_{a2}C_2$.
