Deacon's process is used for the manufacturing of _____.

The correct answer is chlorine.

Key Points

Deacon’s process:

• The deacons process is an oxidation-reduction process.
• In this process chlorine (Cl2) is produced from the reaction of HCl and O2.
• Here HCl acts as a reducing agent and O2 acts as an oxidizing agent.
• In this process, a catalyst cupric chloride (CuCl2) is used.

4HCl + O2 → 2Cl 2 + 2H2O

• Hydrochloric acid is a strong acid & with strong corrosive properties. 
• It is a dangerous and destructive compound as it releases a large amount of chlorine gas which can affect our skin.
• It is produced by adding hydrochloride gas to water.
• It is used for household purposes like toilet cleaners, rust removers, etc

Bleaching powder:

• The chemical formula of bleaching powder is CaOCl2.

• Bleaching powder is a stable, inorganic compound that is chemically known as calcium hypochlorite.
• It is extensively used as a bleaching and disinfecting agent.
