Question

how is bleaching powder manufactured? write its uses​

Answer 1

Preparation of Bleaching Power :

Chlorine gas is produced during electrolysis of aqueous sodium chloride.

This chlorine gas is used for the manufacture of bleaching powder.

Bleaching powder is produced by the action of a chlorine on slaked lime.

Uses of Bleaching Power :

It is used for bleaching cotton and linen in the textile industry for bleaching wood pulp in paper industry for bleaching washed clothes in laundry.

Used as an oxidizing agent in many chemical industries.

Used for disinfecting drinking water to make it free of germs.

Used as a reagent in the preparation of chloroform.

☞ Preparation of Bleaching Powder

✒ Bleaching powder is synthesized by the action of chlorine gas (produced from the chlor-alkali process) on dry slaked lime (Ca(OH)2).

Equation :-

✒ Ca(OH)2 + Cl2 → CaOCl2 + H2O

☞ Uses of bleaching powder :-

✒ It is used as bleaching agent in textile industry and paper factories.

✒ It is used as an oxidising agent in chemical industries.

✒ It is used as disinfectant for drinking water, to make it germ free.

➪ What is the Chemical Name of Bleaching Powder?

✒ The chemical name of bleaching powder is Calcium Oxychloride .

➪ Common Salt (Sodium Chloride)

✒ Common salt is formed by the reaction between hydrochloric acid and sodium hydroxide.

✒ Its chemical name is sodium chloride (NaCl).

✒ It exists as an important raw material for the production of various chemical compounds such as caustic soda (sodium hydroxide), bleaching powder (CaOCl2), etc.

➪ What is Bleaching Powder ?

✒ Bleaching powder is a pale yellowish powder existing with a strong smell of chlorine.

✒ It is soluble in water but due to the presence of impurities, we never observe a clear solution.

✒ Its chemical formula is CaOCl2 with its chemical name as Calcium hypochlorite.

➪ What is the formula for bleaching powder?

✒ Bleaching Powder’s chemical formula is CaOCl2 and is called Calcium Oxychloride. It is prepared on dry slaked lime by chlorine gas.

➪ Is bleaching powder acidic or basic?

✒ Bleaching powder is basic in character. It gives calcium chloride, chlorine and water when bleaching powder reacts with hydrochloric acid.

➪ What is the pH value of bleaching powder?

✒ Bleach usually contains 5% sodium hypochlorite, which gives the skin a pH of about 11 and makes it mildly irritating.
