A metal carbonate X on reacting with an acid gives a gas which when passed through a solution of Y gives a carbonate back. On the other hand, a gas G that is obtained at anode during electrolysis of brine is passed on dry Y, it gives a compound Z, used for disinfecting drinking water. Indentify X, Y, G and Z.
