Equal volumes of three strong acid solutions of pH 3, 4, and 5 are mixed. What is the ion concentrat — Ionic Equilibrium Chemistry Question

💡 Solution & Explanation

$[H^+]_{mix} = (10^{-3} + 10^{-4} + 10^{-5}) / 3 = (100 + 10 + 1) \times 10^{-5} / 3 = 111 \times 10^{-5} / 3 = 3.7 \times 10^{-4} \text{ M}$.
