Question

Why are the aqueous solutions of ammonium acetate and sodium chloride neutral in nature? Explain in detail and mention the difference in the hydrolysis of the two.

Accepted Answer

Ammonium acetate when dissolved in water is hydrolysed to form ammonium hydroxide and acetic acid. Ammonium hydroxide and acetic acid both are weak alkali and acid respectively hence the solution is neutral in nature.

Salts formed by the neutralization of weak acid and weak base are acidic, basic or neutral depending on the nature of acids and bases involved. For example: ${CH}_{3} {COONH}_{4}$ . General mechanism for the hydrolysis of ions formed from these salts,

${CH}_{3} {COO}^{-} + {NH}_{4}^{+} + H_{2} O ⇌ {CH}_{3} COOH + {NH}_{4} OH$ .

Salts formed by the neutralization of strong acid and strong base are neutral in nature as the bonds in the salt solution will not break apart. They generally get hydrated but do not hydrolyse. Therefore, such salts are generally known as neutral salts. For example: $NaCl$ .

Why are the aqueous solutions of ammonium acetate and sodium chloride neutral in nature? Explain in detail and mention the difference in the hydrolysis of the two.
