Quizplus · Accepted Answer

The solution has a hydrogen ion concentration of 3.25 × 10^-6 M, which is greater than the neutral point of 7 (pH 7), indicating an acidic solution. The hydroxide ion concentration can be calculated using the Kw equation: Kw = [H+][OH-] = 1.0 × 10^-14.
So, [OH-] = Kw/[H+] = (1.0 × 10^-14)/(3.25 × 10^-6)
= 3.08 × 10^-9 M
Therefore, the solution is acidic with a hydroxide ion concentration of 3.08 × 10^-9 M. The best choice is option B.
