Calculate the hydronium ion concentration in an aqueous solution that contains 2.50 × 10^-⁶ M in hydroxide ion. A) 4.00 × 10^-⁷ M B) 4.00 × 10^-⁸ M C) 4.00 × 10^-⁹ M D) 5.00 × 10^-⁹ M

Question

Quizplus · Accepted Answer

The product of the concentrations of hydronium and hydroxide ions in water is 1.0 × 10^-14 at 25°C. Therefore, [H₃O⁺] = 1.0 × 10^-14 / [OH⁻] = 1.0 × 10^-14 / 2.50 × 10^-6 = 4.00 × 10^-9 M.
