Match the columns.    
              Column I                                                      Column II
A) NaCl                                                   (P) Cationic hydrolysis
B) Na2CO3                                              (Q) Anionic hydrolysis
C) NH4Cl                                                 (R) pH = 7.0 at 25oC
D) CH3COONH4                                      (S) pH < 7.0 at 25oC
(T) pH > 7.0 at 25oC
Ka, CH3COOH  = Kb, NH4OH

  1. A → Q; B → R, T; C → P, S; D → P, Q, R 
  2. A → Q; B → R, T; C → P,Q,R, S; D → P 
  3. A → P; B → R, T; C → P,Q,R, S; D → Q  
  4. A → R; B → Q, T; C → P, S; D → P, Q, R 

The correct answer is: A → R; B → Q, T; C → P, S; D → P, Q, R


    Sol: NaCl is salt of a strong acid and strong base, Na2CO3 is salt of weak acid strong base.
    NH­4Cl is salt of a strong acid strong base CH3COONH4 is a salt of weak acid and weak base.
