Expert Answer
H2SO4
2H+ + SO42-
H2O H+ + OH-
At cathode:
H++ e- H
H + H H2
At anode:
OH- OH + e-
4OH 2 H2O + O2
The sulphate ions remain unchanged.
Q = 2 F
At anode,
2F of electricity will release 32 g of oxygen gas
1Fof electricity will release 16 g of oxygen gas
At cathode,
2 F of electricity will release 2 g of hydrogen gas
1F of electricity will release 1g of hydrogen gas
