Hydrolysis of salt of weak acid and weak base
WebAnswer: NaCN is a salt of weak acid (HCN) and strong base (NaOH). The degree of hydrolysis (h) for such as salt can be calculated by using the following formulae: h = K W K a × C h = 10 − 14 6.2 × 10 − 10 × 10 − 2 = 0.0401 Thus, % hydrolysis = … Web7 apr. 2024 · Salt of weak acid and weak base undergoes both cationic and anionic hydrolysis. In cationic hydrolysis it gives a weak base and in anionic hydrolysis it gives a weak acid.
