Match the following List-I List-II (A) Aq . Solution of AlCl 3 (I) Basic (B) Aq . solution of CH 3 COONa (II) Acidic (C) Aq . solution of KCl (III) Highly conductive (D) Al 2 O 3 (IV) Strongly basic (V) Amphoteric The correct match is

Options

  1. AA B C D II I III V
  2. BA B C D I III IV V
  3. CA B C D III II I V
  4. DA B C D IV V II I

Correct answer

A. A B C D II I III V

Step-by-step solution

AlCl 3   is a salt of weak base and strong acid, it undergoes cationic hydrolysis Al + 3 + 3 H 2 O → Al ( OH ) 3 + 3 H + H + ions are released in to the solution.Hence, the aqueous solution of AlCl 3   turns acidic in nature. Aqueous solution of CH 3 COONa 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. CH 3 COO - + H 2 O → CH 3 COOH + OH - Al 2 O 3 is amphoteric in nature as it reacts with both ac
