What Is the Faraday's Law of Electrolysis & Electroplating Calculator?
Faraday's Laws of Electrolysis were published by Michael Faraday in 1834, founding the science of quantitative electrochemistry.
How Does the Faraday's Law of Electrolysis & Electroplating Calculator Work?
Each metal ion requires a specific integer count of electrons (z) to reduce from solution onto the electrode surface.
Faraday's Law of Electrolysis & Electroplating Calculator Formula & Variables
The core mathematical equation utilized by this calculator is expressed as:
m = \frac{I \cdot t \cdot M}{z \cdot F}, \quad F = 96485.33 \text{ C/mol}
Plated mass m is proportional to total charge Q = I·t and molar mass M, divided by ion valence z times Faraday constant F.
