Question

Quizplus · Accepted Answer

KCH₃CO₂ is a salt of a weak acid (CH₃CO₂H) and a strong base (KOH). It hydrolyzes in water to form CH₃CO₂⁻, which reacts with water to produce OH⁻. The pH can be calculated using the formula pH = 14 - pOH, where pOH = 0.5(pKb - log[C]), and pKb = 14 - pKa. Substituting the given values, the pH is approximately 9.25.
