A galvanic cell uses the energy released during a spontaneous reaction to generate electricity and is often called an electrolytic cell.

The positive electrode in a galvanic cell is the anode.

In galvanic cells, reduction occurs at the cathode.

The flow of electrons in galvanic cells is from the anode to the cathode.

Which electrode will increase in size as the spontaneous reaction takes place?

What is the anode in this sample galvanic cell set-up?
