🧪 Chemistry Electrochemistry Simulation

Interactive 3D concentration cell: two Cu/Cu²⁺ half-cells at different concentrations generate an EMF from the Nernst equation alone. Adjust concentrations, temperature and load resistance, close the circuit and watch the cell discharge toward equilibrium.

Two copper electrodes sit in Cu²⁺ solutions of different concentration, joined by a salt bridge and an external wire — no two different metals, no two different half-reactions, just the same redox couple at two concentrations. That mismatch alone drives a real voltage, computed live from the Nernst equation as you move the concentration sliders. Close the circuit and watch it work: electrons animate through the external wire from the dilute (anode) side to the concentrated (cathode) side, ions migrate through the salt bridge to preserve neutrality, and both concentrations visibly drift toward each other as the cell discharges and its EMF decays toward zero — exactly the thermodynamic dead end every concentration cell runs down to.
