Show answer & explanation
Correct answer: A
Bleaching powder is chemically known as Calcium Oxychloride and is commonly represented as Ca(OCl)₂ (Calcium Hypochlorite for bleaching action).
The bleaching action is due to the release of nascent oxygen through hypochlorite ions, which oxidize colored substances and make them colorless.
The nascent oxygen [O] is responsible for the bleaching effect.
Therefore, the active ingredient responsible for bleaching action is Ca(OCl)₂.
