The bleaching action of bleaching powder is due to the formation of:

Options

  1. AC a C l 2
  2. BC a S O 4
  3. CH C l O
  4. DC a ( C l O 3 ) 2

Correct answer

C. H C l O

Step-by-step solution

In presence of dil. Acids, bleaching powder loses oxygen. 2 C a O C l 2 + H 2 S O 4 → C a C l 2 + C a S O 4 + 2 H C l O H C l O → H C l + O This oxygen is used for oxidation - bleaching.
