A metal carbonate $X$ on treatment with a mineral acid liberates a gas which when passed through an aqueous solution of a substance $Y$ gives back $X$ . The substance $Y$ on reaction with the gas obtained at the anode during electrolysis of brine gives a compound $Z$ which can decolourise coloured fabrics. The compounds $X, Y$ and $Z$ respectively are:

C a C O_{3}, C a (O H)_{2}, C a O C l_{2}

Solution

The correct option is A $C a C O_{3}, C a (O H)_{2}, C a O C l_{2}$
Option $(A)$ is correct.
The equations are as follows:
$C a C O_{3} [X] + 2 H C l \to C a C l_{2} + H_{2} O + C O_{2}$
$C a (O H)_{2} [Y] + C O_{2} \to C a C O_{3} [X] + H_{2} O$
During electrolysis of brine, chlorine gas is obtained at anode.
$C a (O H)_{2} + C l_{2} \to C a O C l_{2} [Z] + H_{2} O$
