Question

Bleaching powder used in Fish pond is working as:
1. Disinfectant
2. Sterelent
3. Snail Controller
4. Parasticide

Answer 1

Correct Answer - Option 1 : Disinfectant

The correct answer is Disinfectant.

• Bleaching powder or Calcium hypochlorite (CaOCl₂) used in Fish pond is working as a disinfectant.
• It is used for the disinfection of water in the treatment process.
• The chlorine released by the Bleaching powder kills Pathogens (Disease-causing Bacteria).
• When bleaching powder dissolves, it reacts with water to under caloric acid (HOCl) and hypochlorite ions (OCl-).
  • Both substances have very distinctive behavior. Underchloric acid is more reactive and is a stronger disinfectant than hypochlorite.
    Underchloric acid is split into hydrochloric acid (HCl) and atom air oxygen (O). The oxygen atom is a powerful disinfectant.
• The disinfecting properties of chlorine in water are based on the oxidizing power of the free oxygen atoms and chlorine substitution reactions.
