State Faraday’s first law of electrolysis. For the electrode reaction Zn2+ + 2e– → Zn(s), What quantity of electricity in coulombs required to deposit one mole of zinc. |
|
Answer» Faraday’s law states that “The amount of chemical reaction which occurs at any electrode during electrolysis by a current is directly proportional to the quanting of electricity passed through the electrolyte. To deposit one mole of zinc 2 × 96500 = 1,93,000 C of electricity is required. |
