Question

Peroxydisulfuric acid (H2S2O8) can be prepared by electrolytic oxidation of H2SO4 as:
2H2SO4H2S2O8+2H++2e.
O2 and H2 are by products. In such on electrolysis 0.87 g of H2 and 3.36 g O2 were generated at STP. Report the mass of H2S2O8 formed in decagram (write nearest integer).

Solution

2H2SO4H2SO8+2H++2e
nH2=0.872=0.435
nO2=0.105
nH2SO8=1(0.435+0.105)0.46
m=0.46×98=45.08 g
m=4 decagram
