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