Select the solution below that is the most acidic. A)[OH^-] = 1.0 × 10^-4 M B)[OH^-] = 1.0 × 10^-5 M C)[OH^-] = 1.0 × 10^-7 M D)[OH^-] = 1.0 × 10^-9 M E)[OH^-] = 1.0 × 10^-11 M

Question

Quizplus · Accepted Answer

The most acidic solution will have the lowest concentration of hydroxide ions, [OH⁻]. A lower [OH⁻] corresponds to a higher [H⁺], making the solution more acidic. [OH⁻] = 1.0 × 10⁻¹¹ M is the lowest concentration of hydroxide ions, thus the most acidic.
