Calculate the pH of a mixture containing of and of . — Ionic Equilibrium Chemistry Question

💡 Solution & Explanation

$H_2SO_4$ provides $2 H^+$. Molarity $M = 1/200$, so Normality $N = 2/200 = 0.01 \text{ N}$. Since both solutions are exactly $0.01 \text{ N } H_2SO_4$, mixing them doesn't change the normality. $[H^+] = 10^{-2} \text{ N} \implies pH = 2.0$.
