When dry slaked lime is chlorinated, what is produced as the main product?

Correct option is C

The correct answer is (c) Calcium Oxychloride.

When dry slaked lime (Ca(OH)2\text{Ca(OH)}_2Ca(OH)₂ is chlorinated, it produces calcium oxychloride (CaOCl2\text{CaOCl}_2CaOCl₂ as the main product. This compound is commonly known as bleaching powder. This reaction is typically carried out to produce bleaching powder, which is an essential disinfectant and bleaching agent.

Reaction:

Ca(OH)₂ + Cl​₂  ​→ CaOCl₂ +H₂O​

Ca(OH)2+Cl2→CaOCl2+H2O\text{Ca(OH)}_2 + \text{Cl}_2 \rightarrow \text{CaOCl}_2 + \text{H}_2\text{O}

In this reaction:

• Dry slaked lime (Ca(OH)2\text{Ca(OH)}_2Ca(OH)₂) reacts with chlorine gas (Cl2\text{Cl}_2Cl₂).
  
• The products are calcium oxychloride (CaOCl2\text{CaOCl}_2CaOCl₂) and water (H2O\text{H}_2\text{O}H₂O).

Uses of Calcium Oxychloride (Bleaching Powder):

1. As a disinfectant for water purification.
2. As a bleaching agent in the textile and paper industries.
3. As an oxidizing agent in various chemical reactions.

Information Booster:

● The chemical name of bleaching powder is calcium oxychloride.
● It is a key disinfectant and bleaching agent widely used in industries.
● Bleaching powder is used to kill bacteria in water, making it safe for drinking.
● It is manufactured by reacting dry slaked lime with chlorine gas.
● Bleaching powder should be stored carefully as it reacts with moisture in the air.

Additional Knowledge:

• (Option a) Hydrochloric Acid: Hydrochloric acid ($\text{HCl}$) is formed primarily by combining hydrogen and chlorine, but it is not a product of this reaction.
• (Option b) Acetic Acid: Acetic acid (CH3COOH\text{CH}_3\text{COOH}CH₃COOH) is an organic acid commonly found in vinegar; it is not involved in this reaction.
• (Option c) Calcium Oxychloride: This is the correct answer, and it is the chemical name for bleaching powder.
• (Option d) Quicklime: Quicklime ($\text{CaO}$), or calcium oxide, is a different compound and is not the product of chlorination in this reaction.
