Question

why calcium off chloride is know as a bleaching powder?​

Answer 1

Answer:

BLEACHING POWDER(CaOCl2)-REASON:

Bleaching powder is chemically, calcium oxy chloride (CaOCl2). Bleaching powder is manufactured using Backmann’s plant in which calcium hydroxide and Chlorine are made to react to create Bleaching Powder.

Bleaching powder is used to bleach cotton and linen in textile industry and wood pulp in paper industry. It is also used to bleach washed clothes in Laundry. Bleaching powder is also used as a disinfectant and germicide, since it liberates chlorine on exposure to the atmosphere which destroys the germs. It is also used for disinfecting water for the same reason. It is also used as an oxidising agent in many chemical industries.

In the presence of a very small amount of dilute acid, it gives nascent oxygen. Due to the evolution of nascent oxygen, it acts as an oxidising and a bleaching agent.

2CaOCl2 + H2SO4 →CaCl2 + CaSO4+2HOCl

2HOCl → 2 HCl + 2 [O]
