WebApr 9, 2024 · One mole of electrons is required for the reduction of one mole of ions. As we know, the Charge on one electron is equal to 1.6021×10-19 C and one mole of electrons is equal to 6.023×1023 electrons. So, charge on one mole of electrons is equal to – (6.023×1023)× (1.6021×10-19C)=96500 C This charge (96500 C) is called 1 Faraday.
