Galvanic & Electrolytic Cell Simulator

This simulation builds a two-electrode electrochemical cell from scratch: choose any pair of metals from magnesium to silver, set each beaker's ion concentration, and watch electrons drift through the external wire while ions migrate through the salt bridge below. Switch between a spontaneous galvanic cell — where the Nernst equation alone decides which rod dissolves and which one plates — and an electrolysis cell, where an external applied voltage can force the reaction to run backwards. Every stat on the left, from E°cell to ΔG, recomputes live as you move the sliders.
