Match the following

  List-I   List-II
(A) Aq. Solution of AlCl3 (I) Basic
(B) Aq. solution of CH3COONa (II) Acidic
(C) Aq. solution of KCl (III) Highly conductive
(D) Al2O3 (IV) Strongly basic
    (V) Amphoteric

The correct match is

  • Correct answer
    A
    ABCDIIIIIIV
  • B
    ABCDIIIIIVV
  • C
    ABCDIIIIIIV
  • D
    ABCDIVVIII

Solution

AlCl3 is a salt of weak base and strong acid, it undergoes cationic hydrolysis

Al+3+3H2O→Al(OH)3+3H+

H+ ions are released in to the solution.Hence, the aqueous  solution of AlCl3  turns acidic in nature.

Aqueous solution of CH3COONa undergoes anionic hydrolysis as it is a salt of weak acid and strong base and the solution will basic in nature due to the release of OH- ions.

CH3COO-+H2O→CH3COOH+OH-

Al2O3 is amphoteric in nature as it reacts with both acids and bases.

Aqueous solution of KCl  is highly conductive in nature as KCl is an ionic compound.

Hence, the correct match is 

  List-I   List-II
(A) Aq. Solution of AlCl3   Acidic
(B) Aq. solution of CH3COONa   Basic
(C) Aq. solution of KCl   Highly conductive
(D) Al2O3   Amphoteric
       

 

Hence, the correct answer is option: 'A'.
