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

Question

Quizplus · Accepted Answer

The most acidic solution has the lowest pH, which corresponds to the highest concentration of H⁺ ions. Since pH + pOH = 14, the solution with the lowest [OH⁻] will have the highest [H⁺] and thus be the most acidic. [OH⁻] = 1.0 x 10⁻¹¹ M corresponds to the highest [H⁺] concentration.
