## FARADAY’S LAWS OF ELECTROLYSIS AND CALCULATIONS

Charge flow during electrolysis The coulomb is the electrolytic unit of charge. A current of one ampere is the rate of flow of charge equal to one coulomb per second. The charge is calculated from the knowledge of the number of seconds for which a steady current is passed. Current in circuit Time taken Total charge 1 ampere 1 second 1 coulomb 1 ampere 10 seconds 10 coulombs 20 amperes 10 seconds 200 coulombs A amperes t seconds At coulombs Therefore charge = quantity of electricity (Q) = I × t Q = I × t Flow of charge required to liberate 1 mole of element during electrolysis Electrolysis always produces chemical reactions. Consider a reaction (at cathode) in which one mole of silver Ag+ ions is discharged and deposited. Ag+ + e– → Ag(s) In this case, 1 mole of electrons (e–) is required to discharge 1… Read More »FARADAY’S LAWS OF ELECTROLYSIS AND CALCULATIONS
