Solution

In chlor-alkali process, chlorine and hydrogen gases are formed as by-products along with sodium hydroxide.

$2 NaCl(aq) + 2 H_{2} O(l) \to 2 {NaOH(aq) + Cl}_{2} {(g) + H}_{2} (g)$

Chlorine gas produces bleaching power when it reacts with lime water ${(Ca(OH)}_{2})$ . Bleaching powder is used as a bleaching agent in chemical industries.

${Ca(OH)}_{2} (s) + {Cl}_{2} (g) \to {CaOCl}_{2} (s) + H_{2} O(l)$

Therefore, X is chlorine gas, and Y is bleaching powder.
