In one of the industrial processes used for manufacture of sodium hydroxide, a gas X is formed as by product. The gas X reacts with lime water to give a compound Y which is used as a bleaching agent in chemical industry. Identify X and Y giving the chemical equation of the reactions involved.
Sodium chloride is subjected to chloralkali process to manufacture sodium hydroxide. Chlorine and hydrogen gas are formed during this process.
2NaCl + 2H2O → 2NaOH +Cl2 +H2
Chlorine reacts with lime water to give bleaching powder.
Ca(OH)2 + Cl2 → CaOCl2 +H2O
X is chlorine. Y is bleaching powder.
