Answer:- Large quantities of chlorine find industrial applications in the bleaching process of wood pulp, a crucial step in the production of paper and rayon, as well as for cotton and textile bleaching. Chlorine plays a pivotal role in the extraction of precious metals like gold and platinum. Its utility extends to the synthesis of various compounds including dyes, pharmaceuticals, and organic substances such as CCl₄ and CHCl₃. Additionally, it is used in the manufacturing of refrigerants. Chlorine is essential for the sterilization of drinking water, ensuring its safety for consumption. This versatile chemical is also employed in the synthesis of toxic gases like phosgene (COCl₂), tear gas (CCl₃NO₂), and mustard gas (Cl.C₂H₄-S – C₂H₄Cl). Chlorine is a key component in the production of important insecticides like DDT and BHC. Its applications span into the manufacturing of vinyl chloride, which serves as a primary material for the production of polyvinyl chloride (PVC) plastics. Chlorine’s significance extends to the production of various industrial compounds, including bleaching powder, aluminum chloride, hydrogen chloride, hypochlorites, chlorates, perchlorates, and more.
