Which from following salts does not undergo hydrolysis ?

Step-by-step solution

Salts of strong acids and strong bases do not undergo hydrolysis because their constituent ions do not react with water to produce H^+ or OH^- ions. Ammonium nitrate is a salt of a weak base ( NH₄OH ) and a strong acid ( HNO₃ ), so it undergoes cationic hydrolysis. Sodium acetate is a salt of a strong base ( NaOH ) and a weak acid ( CH₃COOH ), so it undergoes anionic hydrolysis. Ammonium cyanide is a salt of a weak base ( NH₄OH ) and a weak acid ( HCN ), so it undergoes both cationic and anionic hydrolysis. Sodium
