Question 1 Report

Which of the following industrial processes is chlorines not used?
Answer Details
Chlorine is not used in the manufacturing of common salt. Common salt, also known as table salt or sodium chloride, is typically obtained through the evaporation of saltwater or brine. Chlorine is not needed in this process because saltwater and brine naturally contain high concentrations of sodium chloride. Chlorine is used in the other three processes listed: - Production of polyvinylchloride (PVC): Chlorine is used to create vinyl chloride monomer, which is then polymerized to form PVC. - Manufacturing of hydrochloric acid: Chlorine is used to react with hydrogen gas to produce hydrochloric acid. - Manufacturing of domestic bleach: Chlorine is used as the active ingredient in many types of bleach, including household bleach.
