Answer 1

Answer:

Chemical formula of Bleaching Powder is CaOCl2 and its Chemical name is Calcium Oxychloride. It is Prepared by Chlorine gas over dry slaked lime. Generally this method is used in large scale preparation of bleaching powder.Ca(OH)2 + Cl2 → CaOCl2 + H2O

Explanation:

Bleaching Powder chemical compositiotn: Ca(ClO)2.CaCl2.Ca(OH)2.2H2O

Bleaching powder is an oxidizing agent.

When bleaching powder is heated with a dilute acid, Cl2 gas is emitted.

Calcium carbonate and chlorine gas is used as raw material in manufacturing bleaching powder.

Answer 2

Answer:

The chemical ne of bleaching powder is calcium oxychloride and it's chemical formula is CaOCl2 .

It is prepared by passing chlorine gas through slaked lime .

Following is the chemical equation for the reaction:

Ca(OH)2 + Cl2 -----> CaOCl2 + H2O

Following are the uses of bleaching powder :

1. For the manufacture of chloroform.
2. As a disinfectant.

Hope this ans would help you
