Consider the salt ammonium fluoride, NH₄F, that is derived from a combination of a weak acid and a weak base as shown below. NH₃ (g) + HF (g)→NH₄F K _b(NH₃) = 1.8×10^{- 5} and K _a(HF) = 6.8×10^{- 4} Which statement listed below is true?

Question

Quizplus · Accepted Answer

The salt NH₄F is acidic when dissolved in water because the Ka of HF (6.8×10⁻⁴) is greater than the Kb of NH₃ (1.8×10⁻⁵), indicating that the acidic component is stronger than the basic component.
