Solution and Explanation
Preparation of Bleaching Powder:
Bleaching powder (CaOCl2) is produced by passing chlorine gas over slaked lime (Ca(OH)2):
\[
Ca(OH)_2 + Cl_2 \rightarrow CaOCl_2 + H_2O
\]
Uses of Bleaching Powder:
1. Disinfection: It is used to purify drinking water.
2. Textile Industry: It is used for bleaching cotton and linen fabrics.
1. Disinfection: It is used to purify drinking water.
