Explained

What is the Galvanic Cell?

Build a battery from two metals and watch electrons flow, with the cell voltage. It runs in your browser, so a change to a setting or a drag on an object shows up at once.

Galvanic cells are batteries. Understanding electrode potentials helps design phones, cars, grid storage and prevent corrosion.

3 steps to your result

Open the tool and follow along. Nothing to install.

In the Galvanic Cell (Voltaic Cell), use the controls to change Left half-cell metal, Right half-cell metal, Your metal X: E°, Your metal Y: E°. The simulation reacts instantly.

Start with this experiment: Build a Zn–Cu cell. Drag any glowing handle, object or slider with your mouse or finger and the Galvanic Cell (Voltaic Cell) responds in real time.

Change one setting at a time and watch which readout moves, then compare it with this idea: Oxidation happens at the anode and reduction at the cathode.

What you get

Key idea 1

Oxidation happens at the anode and reduction at the cathode.

Key idea 2

Electrons flow from anode to cathode through the wire.

Key idea 3

E°cell = E°cathode − E°anode. A positive value means the cell is spontaneous.

Experiment 1

Build a Zn–Cu cell.

Experiment 2

Try Mg with Ag.

Experiment 3

Close the circuit and watch the electrodes.

Questions people ask

Which way do electrons flow in a galvanic cell?

From the anode (where oxidation happens) through the wire to the cathode (where reduction happens).

What does the salt bridge do?

It lets ions move between the two half-cells to keep each solution electrically neutral, which completes the circuit.

Is the Galvanic Cell (Voltaic Cell) free to use?

Yes. The Galvanic Cell (Voltaic Cell) is free, needs no signup or download and runs in your web browser. It is part of the Electrochemistry group of AZRS simulations.

Does the Galvanic Cell (Voltaic Cell) work on a phone or tablet?

Yes. The Galvanic Cell (Voltaic Cell) takes touch input as well as mouse input, so you can use its 4 adjustable settings with a finger. A larger screen makes the controls and graphs easier to read.

How do I use the Galvanic Cell?

1. In the Galvanic Cell (Voltaic Cell), use the controls to change Left half-cell metal, Right half-cell metal, Your metal X: E°, Your metal Y: E°. The simulation reacts instantly. 2. In the Galvanic Cell (Voltaic Cell), press "Close the circuit", "Reset" to start, reset or change what is happening. 3. Start with this experiment: Build a Zn–Cu cell. Drag any glowing handle, object or slider with your mouse or finger and the Galvanic Cell (Voltaic Cell) responds in real time. 4. Change one setting at a time and watch which readout moves, then compare it with this idea: Oxidation happens at the anode and reduction at the cathode.
