The deciding factor that makes HF a weak acid is that A) HF has a large bond energy. B) F₂ has a small bond energy. C) the entropy for hydration of F^- is a large negative value. D) the enthalpy of hydration of F^- is negative. E) F^- has the largest ionization energy of all the halide ions.

Question

Quizplus · Accepted Answer

The entropy for hydration of F^- is a large negative value.This is because the small size and high charge density of F^- make it difficult for water molecules to solvate it. As a result, the entropy change for the hydration of F^- is negative, which makes HF a weak acid.
