Question

Which of the following solutions is acidic A) [OH^-] = 1.0 x 10^-7 M B) [OH^-] > 1.0 x 10^-7 M C) [OH^-] = 1.0 x 10^-10 M D) [H₃O⁺] = 1.0 x 10^-10 M E) [H₃O⁺] < 1.0 x 10^-7 M

Quizplus · Accepted Answer

A solution is acidic if the concentration of hydronium ions [H₃O⁺] is greater than 1.0 x 10^-7 M. If [OH^-] = 1.0 x 10^-10 M, then [H₃O⁺] = 1.0 x 10^-4 M, which is greater than 1.0 x 10^-7 M, making the solution acidic.
