What is the pH of an aqueous solution that contains 5.3 *10¹⁷ OH^- ions per liter of solution? A)5.30 B)6.06 C)7.94 D)8.70 E)11.3

Question

Quizplus · Accepted Answer

To find the pH, we need to determine the concentration of H+ ions in the solution. Since OH- ions are given, we can use the Kw expression:
Kw = [H+][OH-]
1.0 x 10^-14 = [H+][5.3 x 10^-10]
[H+] = 1.88 x 10^-5
pH = -log[H+] = 7.94
Therefore, the correct answer is (C) 7.94.
