Question

Which of the following solutions is acidic A) [H₃O⁺] = 7.0 x 10^-7 M B) [H₃O⁺] = 1.5 x 10^-10 M C) [H₃O⁺] < 7.0 x 10^-7 M D) [H₃O⁺] > 7.0 x 10^-7 M E) [H₃O⁺] = 1.0 x 10^-14 M

Quizplus · Accepted Answer

A solution is acidic if the concentration of hydronium ions [H₃O⁺] is greater than 1.0 x 10^-7 M, which corresponds to a pH less than 7. Therefore, option D, where [H₃O⁺] > 7.0 x 10^-7 M, indicates an acidic solution.
