Question

Quizplus · Accepted Answer

NaCH₃CO₂ is a salt of a weak acid (CH₃COOH) and a strong base (NaOH). It hydrolyzes in water to form OH⁻ ions, making the solution basic. The pH is calculated using the formula pH = 14 - 0.5(pKa - log C), where C is the concentration of the salt. This gives a pH of approximately 9.32.
