A solution with a hydroxide ion concentration of 4.15 × 10^-4 M is ________ and has a hydrogen ion concentration of ________. A)acidic,2.41 × 10^-10 M B)acidic,2.41 × 10^-11 M C)basic,2.41 × 10^-10 M D)basic,2.41 × 10^-11 M

Question

Quizplus · Accepted Answer

The solution is basic because the hydroxide ion concentration is greater than 1 × 10^-7 M. The hydrogen ion concentration can be calculated using the formula [H+][OH-] = 1 × 10^-14, which gives [H+] = 2.41 × 10^-11 M.
