Question

Quizplus · Accepted Answer

A solution with a hydrogen ion concentration of 3.25 × 10^-5 M is acidic because the hydrogen ion concentration is greater than the hydroxide ion concentration in an acidic solution. 
To find the hydroxide ion concentration, we can use the equation Kw = [H+][OH-] where Kw is the ion product constant for water (1.0 x 10^-14 M^2). 
Solving for [OH-], we get [OH-] = Kw/[H+] = 1.0 x 10^-14 / 3.25 x 10^-5 = 3.08 x 10^-10 M. 
Therefore, the solution is acidic with a hydroxide ion concentration of 3.08 x 10^-10 M, which corresponds to option B.
