Answer 2

The correct option is- (D) All the above.

Chlorine is used in many industries because of its disinfecting and bleaching properties.

• Chlorine is very reactive, hence many non-ferrous metals are extracted from their ores by the chlorination process. Chlorination is widely used in the extraction of gold and platinum.
• Moist chlorine acts as a bleaching agent as it produces nascent oxygen. Hence, it is used in paper industries to bleach wood pulp.
• As a disinfectant, it is used in sewage treatment plants to clean dirty water. It helps in sterilizing drinking water by killing bacteria.
