Which of the following correctly labels the salts?

HF (Ka = 7.2 × 10–4)

NH3 (Kb = 1.8 × 10–5)

HCN (Ka = 6.2 × 10–10)

 

◦ NaCN = acidic, NH₄F = basic, KCN = neutral
◦ NaCN = acidic, NH₄F = neutral, KCN = basic
◦ NaCN = basic, NH₄F = basic, KCN= neutral
◦ NaCN = basic, NH₄F = neutral, KCN = basic
◦ NaCN = basic, NH₄F = acidic, KCN = basic
