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 1.0 × 10^-7 mol L^-1. The hydrogen ion concentration can be calculated using the ion product of water (Kw = 1.0 × 10^-14), giving 2.41 × 10^-9 mol L^-1.
