A solution with a hydroxide ion concentration of 4.15 × 10^-6 mol L^-1 is ________ and has a hydrogen ion concentration of ________. A)acidic, 2.41 × 10^-8 mol L^-1 B)acidic, 2.41 × 10^-9 mol L^-1 C)basic, 2.41 × 10^-8 mol L^-1 D)basic, 2.41 × 10^-9 mol L^-1

Question

Quizplus · Accepted Answer

The solution is basic because the hydroxide ion concentration is greater than 1 × 10^-7 mol L^-1. The hydrogen ion concentration is calculated using Kw = [H+][OH-] = 1 × 10^-14, resulting in [H+] = 2.41 × 10^-9 mol L^-1.
