Question

Bleaching power is obtained by the action chlorine gas and
(A) Dilute solution of Ca(OH)2
(B) Concentrated solution of Ca(OH)2
(C) Dry CaO
(D) Dry slaked lime.

Answer 1

Correct option (d) dry slaked lime. Explanation : Cl2 gas reacts with dry slaked lime, Ca(OH2) to give bleaching powder

Answer 2

Answer:

(D). Dry slaked lime.

Explanation:

Bleaching power is obtained by the action chlorine gas and dry slaked lime. In this process, we get chlorine gas from the electrolysis of brine. Then this chlorine gas is passed through the Dry slaked lime. It produces calcium oxychloride and water. By using the method of crystallization process, we get the crystal of calcium oxychloride in solid state. It is chemically known as calcium oxychloride, calcium hypochlorite or Chloride of lime.

Reaction:

Ca(OH)2(l) + Cl2(g) --------> CaOCl2 (aq) + H2O(l)
