Bleaching powder is produced by the action of chlorine gas on dry slaked lime [Ca(OH)2]. This chemical reaction results in the formation of bleaching powder, which is represented as CaOCl2.

Chlorine gas, a product of the chlor-alkali process, is commonly utilized for the manufacture of bleaching powder. This compound is extensively employed as a bleaching agent in various industries, including textile, pulp, and paper.

Near the cathode during the chlor-alkali process, a useful solution of sodium hydroxide (NaOH) is formed. This solution has various industrial applications, including in the production of soaps, detergents, and paper.

During the chlor-alkali process, chlorine gas (Cl2) and sodium hydroxide (NaOH) are formed as products through the electrolysis of an aqueous solution of sodium chloride (brine).

The process is called the chlor-alkali process, wherein electricity is passed through an aqueous solution of sodium chloride (brine), resulting in the production of chlorine gas and sodium hydroxide.
