Question

Quizplus · Accepted Answer

NH₄Cl is a salt of a weak base (NH₃) and a strong acid (HCl). It hydrolyzes in water to form NH₄⁺, which acts as a weak acid. The pH can be calculated using the formula pH = 14 - pOH, where pOH is found using the Kb of NH₃ and the concentration of NH₄⁺. The correct pH is approximately 4.74.
