Expert Answer:

Equation of electrolysis of dil. H2SO4 -
At space Cathode minus
2 straight H to the power of plus space plus 2 straight e to the power of minus space rightwards arrow straight H subscript 2

At space Anode minus
2 OH to the power of minus rightwards arrow straight O subscript 2 plus 2 straight H subscript 2 straight O plus 4 straight e to the power of minus

Overall space reaction space would space be minus

straight H subscript 2 straight O rightwards arrow 2 straight H subscript 2 space end subscript plus straight O subscript 2


Amount space of space substance space at space cathode equals 2 space moles space of space straight H subscript 2 space equals 4 space straight g
Amount space of space substance space liberated space at space anode equals space 1 space mole space of space straight O subscript 2 space equals 32 space straight g

Ratio space of space substances space liberated space on space cathode space and space anode minus
4 colon 32
1 colon 8
