Correct Answer: CaOCl 2


Solution : The correct answer is CaOCl 2 .

Bleaching powder is typically produced by the reaction of calcium Hydroxide [Ca(OH) 2 ] with chlorine gas (Cl 2 ). The chemical reaction is as follows:

Ca(OH) 2 + Cl 2 → Ca(ClO) 2 + H 2 O

In this reaction, Calcium Hydroxide reacts with Chlorine gas to form calcium Hypochlorite and water. Calcium Hypochlorite, or bleaching powder, has the chemical formula Ca (ClO) 2 .
