The products obtained at the cathode and anode respectively during the electrolysis of aqueous K ₂ SO ₄ solution using platinum electrodes are

Step-by-step solution

K ₂ SO ₄ 2 ~K ⁻¹+ SO ₄²⁻ Due to platinum electrodes, self ionization of water will take place. H ₂ O 2 H ⁺+ OH ⁻ At cathode: 2 H ⁺+2 e - H ₂ At anode: OH 2 H ₂ O + O ₂+4 e Due to lower electrode potentials, H ₂ gas will generate at cathode and O ₂ gas will generate at anode.
