What is the pH of solution made by mixing equal volumes of , , ? — Ionic Equilibrium Chemistry Question

💡 Solution & Explanation

All three components are strong acids, and they are provided with identical normalities ($0.1\text{ N}$). Normality directly reflects the concentration of available $\text{H}^+$ equivalents. Mixing equal volumes of solutions that all have an $\text{H}^+$ concentration of $0.1\text{ N}$ yields a final mixture with the exact same normality, $0.1\text{ N}$ (or $0.1\text{ M}$ in terms of $\text{H}^+$). The $\text{pH} = -\log(0.1) = 1$.
