Faraday's laws tie electric charge to chemistry: the mass deposited equals (Q/F)·(M/z), where Q is total charge, F the Faraday constant, and z the ion charge. Double the current or time and you double the metal plated. Educational tool.

Charge passed3600 C

Moles deposited0.0187 mol

Mass deposited1.185 g

Governing equation

m = \frac{I t M}{n F} = \frac{2 \cdot 1800 \cdot 63.5}{2 \cdot 96485} = 1.185 g

Reading this result: Passing 3600 C plates 1.185 g of Copper. Each Copper ion carries 2 electrons, so it takes 2× the charge to deposit one atom — a higher ion charge means less metal per coulomb, even at the same current.

About this simulation

The full Electrolysis tool models a battery cell with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
