On electrolysis of conc. H2so4 solution, product obtained at anode is

Answer 1

Hey Dear,

◆ Answer -

On electrolysis of conc.H2SO4 solution, product obtained at anode is S2O6²⁻.

◆ Electrolyis of sulphuric acid -

(1) Electrolysis of dil. H2SO4 -

At Cathode : 2H+ + 2e- → H2

At Anode : 2H2O → O2 + 4H+ + 4e-

(2) Electrolysis of conc. H2SO4 -

At Cathode : 2H+ + 2e- → H2

At Anode : 2SO4²⁻ → S2O6²⁻ + 2e-

Hope this helps you. Keep asking questions.
