The chemical representation of bleaching powder is CaOCl2. Its actual composition is noted to be complex due to the presence of various chemical species in the compound.

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).
