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 that can decolourise the fabrics. The compounds X, Y and Z respectively are:
