9.11 Electrolysis and Faraday’s Law

Calculate the amount of charge flow based on changes in the amounts of reactants and products in an electrochemical cell.

• Faraday’s laws can be used to determine the stoichiometry of the redox reaction occurring in an electrochemical cell with respect to the following:
  • i. Number of electrons transferred
  • ii. Mass of material deposited on or removed from an electrode (as in electroplating)
  • iii. Current
  • iv. Time elapsed
  • v. Charge of ionic species EQN: I = q/t
