Quizplus · Accepted Answer

When a weak acid is neutralized by a strong base, the resulting solution will have a pH greater than 7. This is because the conjugate base of the weak acid will hydrolyze to form hydroxide ions (OH-) which increase the pH of the solution. In this case, acetic acid (CH3COOH) will be neutralized by NaOH to form sodium acetate (CH3COO-). The pH of the resulting solution will be greater than 7.
