The pH of a solution that is 0.20 M CH₃COOH and 0.20 M CH₃COONa should be higher than the pH of a 0.20 M CH₃COOH solution.

Question

Quizplus · Accepted Answer

The addition of CH₃COONa to the solution will act as a buffer, which will resist changes in pH when small amounts of acid or base are added. The buffer will preferentially react with any added acid, preventing the pH from decreasing as much as it would in the absence of the buffer. Therefore, the pH of the solution containing both CH₃COOH and CH₃COONa should be higher than the pH of the solution containing only CH₃COOH.
