The pH of an aqueous solution at 25.0 °C is 10.55.What is the molarity of $ \mathrm{H}^{+} $ ? A)2.8 × 10^-11mol L^-1 B)3.5 × 10¹⁰mol L^-1 C)3.5 × 10^-4mol L^-1 D)3.5 mol L^-1 E)2.36 mol L^-1

Question

Quizplus · Accepted Answer

The pH is given as 10.55, which means the concentration of $ \mathrm{H}^{+} $ ions is $ 10^{-10.55} $ mol L$^{-1}$. Calculating this gives approximately 2.8 × 10$^{-11}$ mol L$^{-1}$.
