A water solution is found to have an OH^- concentration of 6.3 × 10−¹⁰. The solution would be classified as: A)acidic. B)basic. C)neutral.

Question

Quizplus · Accepted Answer

The given concentration of OH- ions (6.3 × 10^-11) indicates a basic solution, as the concentration of OH- ions is higher than what would be found in a neutral solution (7 × 10^-7 for H+ in neutral, meaning OH- would also be 7 × 10^-7 in a perfectly neutral solution due to the product of [H+][OH-] being 1 × 10^-14 at 25°C).
