Bleaching powder is prepared by passing chlorine gas over dry slaked lime (calcium hydroxide).
Chemical Equation:
Cl2 + Ca(OH)2 → CaOCl2 + H2O
Here,
- Ca(OH)2 = Calcium hydroxide (slaked lime)
- Cl2 = Chlorine
- CaOCl2 = Bleaching powder
- H2O = Water
So, the base used is Calcium hydroxide.

Manufacture of Bleaching Powder
Bleaching powder, also known as calcium hypochlorite, is a chemical compound widely used for disinfection and bleaching purposes. The base used in its manufacture is crucial for understanding its production process.
Key Ingredient: Calcium Hydroxide
- The correct answer is Calcium Hydroxide (option D).
- Calcium hydroxide, also known as slaked lime, is a key raw material in the production of bleaching powder.
Production Process
- The manufacturing process involves the reaction of calcium hydroxide with chlorine gas.
- The chemical reaction can be summarized as:
- 2Ca(OH)2 + Cl2 → Ca(OCl)2 + CaCl2 + 2H2O
- In this reaction, chlorine gas reacts with calcium hydroxide to form calcium hypochlorite (bleaching powder) along with calcium chloride and water.
Other Bases and Their Uses
- Magnesium Hydroxide: Commonly used as an antacid and laxative, not relevant for bleaching powder.
- Sodium Hydroxide: Used for soap making and as a strong cleaning agent, not involved in bleaching powder production.
- Potassium Hydroxide: Primarily used in fertilizer and biodiesel production, not related to bleaching powder.
Conclusion
- The choice of calcium hydroxide in the manufacturing process highlights its importance in producing effective bleaching agents.
- Understanding this process is essential for students studying chemistry, especially in the context of reactions and industrial applications.
