A) Ammonium sulphate
B) Sodium sulphate
C) Copper sulphate
D) All the salts will hydrolyse
Correct Answer: A
Solution :
Key Idea: (i) Salts of strong acids and strong bases are not hydrolysed. (ii) The salts of weak acid and strong base or strong acid and weak base or weak acid and weak base are hydrolysed. Ammonium sulphate: \[[{{(N{{H}_{4}})}_{2}}S{{O}_{4}}]\] is salt of strong acid \[{{H}_{2}}S{{O}_{4}}\] and weak base \[N{{H}_{4}}OH\]. \[\therefore \] It is hydrolysed. Copper sulphate \[[CuS{{o}_{4}}]\] is salt of weak base \[[Cu{{(OH)}_{2}}]\] and strong acid \[{{H}_{2}}S{{O}_{4}}\]. \[\therefore \] It is hydrolysed. Sodium sulphate \[(N{{a}_{2}}S{{O}_{4}})\] is salt of strong base \[NaOH\]and strong acid \[{{H}_{2}}S{{O}_{4}}\] \[\therefore \] It is not hydrolysed.
