How is sodium chloride made?

Production. Sodium chloride is found abundantly in nature. Most of it is dissolved in water, to form sea water; in part it is found as a solid mineral in mainland deposits (in this case it is called "rock salt").

How is chlorine produced?

How it is produced. Chlorine is produced by passing electric current through a brine solution, which is a solution obtained by dissolving sodium chloride in water. In addition to chlorine, this process also produces hydrogen (H2) and caustic soda (NaOH, sodium hydroxide).
