Question

During electrolysis of an aqueous solution of sulfuric acid between platinum electrode two t000ype of anions migrate towards the anode but only one of them is discharged. Do you notice any change in colour state why quora

Answer 1

Hey,

There are two chemical substance in solution that is H2O and H2SO4. H2O will give OH- ion and H2SO4 will give SO42- ions. At the anode the concentration of hydroxyl ions is too low to maintain a reaction and the sulphate ions are not oxidized but remain on in solution at the end. Water molecules must be the species reacting at the anode.
2 H2O ==> O2 + 4 H+ + 4 e-

HOPE IT HELPS YOU:-))
