Calculate the hydroxide ion concentration in an aqueous solution with a pH of 4.33 at 25 °C. A) 2.1 × 10^-10 mol L^-1 B) 9.7 × 10^-10mol L^-1 C) 4.7 × 10^-5 mol L^-1 D) 3.8 × 10^-5 mol L^-1 E) 6.3 × 10^-6 mol L^-1

Question

Quizplus · Accepted Answer

The pH of the solution is 4.33, so the pOH is 14 - 4.33 = 9.67. The hydroxide ion concentration is calculated using [OH⁻] = 10^(-pOH) = 10^(-9.67) ≈ 2.1 × 10^-10 mol L^-1.
