Question

Bleaching powder is correctly represented as
A. $CaOC{{l}_{2}}$ ​
B. $CaO$
C. $CaOCl$
D. $Ca(OCl)Cl$

Answer 1

Hint: Bleaching powder is actually a basic compound. Chlorine is highly used as a bleaching agent, sterilisation and preparation of antiseptic. The nascent oxygen prepared by chlorine in presence of moisture helps in the bleaching.

Complete Step by Step Answer:
Chlorine is a halogen element.
The chemical formula of bleaching powder is $Ca(OCl)Cl$ . Thus bleaching powder contains chlorine atoms and calcium atoms. So, chlorine is widely used as a bleaching agent.
Thus we can write that the bleaching powder is correctly represented as $Ca(OCl)Cl$.
Thus the correct option is D.

Additional information: Bleaching powder contains calcium and chlorine as major elements along with oxygen atoms. The uses of bleaching powder are as follows:
- Bleaching powder is used to kill bacteria.
- It is highly used to clean many areas, drain etc as it kills the bacteria, virus, mosquito, fly etc which causes many harmful diseases.
