Faraday's Law of Electrolysis
Formula
m = (I × t × M) / (z × F)
Where:
The mass deposited is proportional to the charge passed and the molar mass, and inversely proportional to the charge number.
Example Calculation
Electroplating copper (M = 63.55, z = 2) with 5 A for 1 hour (3600 s).
- 01m = (I × t × M) / (z × F)
- 02m = (5 × 3600 × 63.55) / (2 × 96485)
- 03m = 1,143,900 / 192,970
- 04m = 5.928 g
