Faraday’s Laws
2. Faraday’s Law
where:
• m is the mass of the substance liberated at an electrode in
grams
• Q is the total electric charge passed through the substance
• F = 96,485 C mol−1 is the Faraday constant
• M is the molar mass of the substance
• z is the valency number of ions of the substance (electrons
transferred per ion)
