50% X on electrolysis at 0∘C gives Y; 'Y' on distillation gives H2O2. Then number of peroxy bonds in X and Y are
1,0
1,2
0,1
0,2
X is H2SO4 and Y is H2S2O8
Question 45. A metal carbonate X on reacts with acid and gives a gas which when passed through a solution Y gives the carbonate back. On the other hand, a gas G that is obtained at the anode during electrolysis of brine is passed on dry Y, it gives a compound Z, used for disinfecting drinking water. Identify X, Y, G and Z.
