Science (086) — AI-generated practice question

Manufacture of Bleaching Powder:
Bleaching powder is manufactured by passing chlorine gas over dry slaked lime [Ca(OH)₂] at about 40°C.

Balanced Chemical Equation:

$$\text{Ca(OH)}_2 + \text{Cl}_2 \rightarrow \text{CaOCl}_2 + \text{H}_2\text{O}$$

(Calcium hydroxide + Chlorine → Bleaching powder + Water)

Two Uses of Bleaching Powder:

1. It is used as a disinfectant and for sterilising drinking water.
2. It is used for bleaching cotton and linen in the textile industry.

This question tests knowledge from the Acids, Bases and Salts chapter. Examiners expect: (1) a one-line description of the manufacturing process mentioning both reactants and the temperature condition, (2) the correctly written and balanced equation with formula CaOCl₂ for bleaching powder, and (3) any two distinct uses. Avoid vague answers — be specific (e.g., "drinking water" not just "water").
