Which of the following salts on hydrolysis would give an alkaline solution?

The salt that would give an alkaline solution upon hydrolysis is CH₃COONa. When CH₃COONa is hydrolyzed, it reacts with water to form acetic acid (CH₃COOH) and sodium hydroxide (NaOH). Sodium hydroxide is a strong base and will dissociate in water to produce hydroxide ions (OH^-), which will increase the pH of the solution and make it alkaline. Acetic acid is a weak acid and will only slightly lower the pH of the solution. On the other hand, NH₄CI, AICI₃, and NH₄NO₃ are all salts that would give an acidic solution upon hydrolysis. When NH₄CI is hydrolyzed, it forms ammonium hydroxide (NH₄OH) and hydrochloric acid (HCI), which is an acidic solution. AICI₃ and NH₄NO₃ would also give acidic solutions upon hydrolysis.
