Enter the desired mass to deposit in grams, the current in amperes, the molar mass of the substance, and the number of electrons per ion. The calculator rearranges Faraday's law to find the time needed.
About the Electrolysis Time Calculator
This calculator is the inverse of Faraday's law of electrolysis. Instead of calculating how much mass is deposited in a given time, it calculates how long electrolysis must run to deposit a target mass. It is useful for planning electroplating operations and industrial electrolysis processes.
Frequently Asked Questions
How is this related to Faraday's law?
This is the same equation rearranged. Faraday's law gives mass from current and time: m = MIt/(nF). This calculator rearranges to solve for time: t = nFm/(MI).
Can I increase the current to reduce time?
Yes. Doubling the current halves the time needed. However, very high currents can cause problems like poor deposit quality, excessive heating, or gas evolution that reduces efficiency.
What affects electrolysis efficiency?
Real electrolysis rarely achieves 100% efficiency. Side reactions (like water electrolysis producing gas), resistance losses, and concentration polarization reduce the actual mass deposited per unit charge.
