What is the pH of a 0.0125 M NaOH solution?

Question

Quizplus · Accepted Answer

NaOH is a strong base that dissociates completely in water to form OH- ions. The concentration of OH- ions in a 0.0125 M NaOH solution would be equal to the concentration of the NaOH itself, which means the [OH-] is 0.0125 M. To find the pH of this solution, we can use the formula pH = -log [H+], where [H+] = (1.0 x 10^-14) / [OH-]. Plugging in the values gives us pH = 12.097. Therefore, the correct answer is choice C.
