Galvanic cells pt 2/3

The oxidation reaction in one of the half-cells liberates electrons, which flow through a metallic conductor of an external circuit, into the other half-cell where reduction occurs, which absorbs electrons.

Beautifully illustrated diagram of a galvanic cell set up with zinc anode on the right sending electrons off to the copper anode to the left, so that zinc goes into solution and copper goes back to being a metal.
