Question

The molar concentration of OH in a water solution is 1.0 *10^-⁹.The pH of the solution is _____ . A) 9.00 B) 5.00 C) > 9.00 D) < 5.00

Quizplus · Accepted Answer

The concentration of OH- is 1.0 * 10^-9, so the concentration of H+ is 1.0 * 10^-5 (since [H+][OH-] = 1.0 * 10^-14). Therefore, the pH is 5.00.
