Acid strength decreases in the series: strongest HSO₄^- > HF > HCN. Which of these species is the weakest base? A)HF B)SO₄^2- C)F^- D)CN^-

Quizplus · Accepted Answer

The weakest base corresponds to the conjugate base of the strongest acid. Since HSO4- is the strongest acid in the series, its conjugate base, SO4^2-, is the weakest base.

Acid Strength Decreases in the Series: Strongest HSO4- > HF

Acid Strength Decreases in the Series: Strongest HSO₄^- > HF
