In one of the industrial processes used for the manufacture of sodium hydroxide, a gas X is formed as a by-product. The gas X reacts with lime water to give a compound Y which is used as a bleaching agent in the chemical industry. Identify X and Y, giving the chemical equation of the reactions involved.

Identification:

X = Chlorine

Y = Bleaching powder

Reaction Involved:

Ca(OH)2 (s) + Cl2 (g) →  CaOCl2 (s) + H2O — Calcium oxychloride (bleaching powder)
