Explanation

Chlorine is widely used for bleaching purposes in industries like paper and textile manufacturing, as well as in water treatment. It's a strong oxidizing agent that breaks down colored organic compounds into colorless products. While other halogens exist, chlorine is the most economically viable and effective for large-scale bleaching applications.
