What happens when bleaching powder reacts with dilute sulphuric acid?

when bleaching powder reacts with dilute sulphuric acid, all the chlorine present in it is liberated. This chlorine acts as a bleaching agent.

How is bleaching powder produced write the chemical reaction?

It can be prepared by passing Cl2 gas into der slaked lime i.e.Ca(OH)2. It is represented by the chemical formula- CaOCl2 but the actual formula is very complex to remember. On reacting with water it forms calcium hydroxide and chlorine gas evolves.

Which gas is evolved when calcium oxychloride reacts with sulphuric acid write chemical equation involved?

Bleaching powder is CaOCl2 (calcium oxychloride). It gives strong smell of chlorine. It reacts with sulphuric acid to form calcium sulphate and chlorine gas is liberated.

What is the chemical name of bleaching powder?

Calcium hypochloriteCalcium hypochlorite / IUPAC ID
Calcium hypochlorite is an inorganic compound with formula Ca(OCl)2. It is the main active ingredient of commercial products called bleaching powder, chlorine powder, or chlorinated lime, used for water treatment and as a bleaching agent.

When bleaching powder reacts with Sulphuric acid __ gas is produced *?

(b) When bleaching powder reacts with dilute sulphuric acid , it produces chlorine gas.

What happens when bleaching powder reacts with dilute acid?

> When bleaching powder is treated with excess of dilute acid, chlorine gas is liberated. > Chlorine gas produced by the action of dilute acid on bleaching powder acts as a bleaching agent.

What happens when bleaching powder reacts with dilute Sulphuric acid give equation of the reaction involved?

(a) Bleaching powder is Calcium oxychloride (CaOCl2). (b) When bleaching powder reacts with dilute sulphuric acid , it produces chlorine gas. CaOCl2 + H2SO4 → CaSO4 + Cl2 + H2O. (c) (i) It is used for disinfecting drinking water supply.

What is the action of Sulphuric acid on bleaching powder?

Bleaching powder reacts with carbon dioxide and produce chlorine gas. Reaction with dilute sulphuric acid: When bleaching powder is treated with an excess of dilute sulphuric acid, all the chlorine present in it is liberated: The amount of chlorine thus set free is called “available chlorine” .

When sulphuric acid is passed through bleaching powder which gas is evolved?

When bleaching powder reacts with dilute sulphuric acid, all the chlorine present in it is liberated. This chlorine acts as a bleaching agent.

Which is the gas coming out from bleaching powder in the presence of water?

Chlorine gas is liberated when bleaching powder reacts with water.

What is bleaching powder How is it prepared write chemical equation involved in the preparation of bleaching powder write two uses of bleaching powder?

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.

What is bleaching powder How is bleaching powder produced?

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