  • Faraday’s Laws for Electrolysis are captured by \(W= \frac{ItM}{Fn}\) where \(M\) is the mass of metal lost/deposited, \(I\) is the current, \(t\) is the time of reaction involving mass-charge transfer \(M\) is the Molar Mass, \(F\) is Faraday’s Constant and \(n\) is the valency change of the metal in the reaction.
  • For alloys, the equivalent \(\displaystyle W={\frac {It}{F\times \sum _{i}^{n}{\frac {X_{i}\times z_{i}}{M_{i}}}}}\) where \(X_{i}\) is the weight fraction of the \(i^{th}\) metal in the alloy.
  • For non-constant current, \(It\) should be replaced by integral of current over time \(\int_0^t I(\tau) d\tau\).
