Galvanic Cells

Splitting a redox reaction in two

An interactive lesson with 5 steps, about 5 minutes: you predict, drag and solve, with instant feedback on every answer. It runs in your browser and needs JavaScript.

What you’ll learn

• Galvanic cell: oxidation and reduction in separate halves, electrons through a wire.
• Negative electrode = oxidised metal; salt bridge carries ions.
• Cell voltage = E(right, reduced) − E(left, oxidised).

Steps

1. Separate the halves
2. Build the Daniell cell
3. Maximum voltage
4. Without the bridge
5. Which way do electrons go?
