Electrolysis Time Calculation
Formula
t = (m × z × F) / (I × M)
Where:
This is a rearrangement of Faraday's Law solving for time.
Example Calculation
Deposit 10 g of copper (M = 63.55, z = 2) using 5 A.
- 01t = (m × z × F) / (I × M)
- 02t = (10 × 2 × 96485) / (5 × 63.55)
- 03t = 1,929,700 / 317.75
- 04t = 6073 s = 101.2 min = 1.69 hr
