A redox reaction is the force behind an electrochemical cell like the Galvanic cell pictured. The battery is made out of a zinc electrode in a ZnSO4 solution connected with a wire and a porous disk to a copper electrode in a CuSO4 solution.

Galvanic Cells (Voltaic Cells) All about Galvanic Cells, which are also called Voltaic Cells. These are devices that use a chemical reaction to create electricity. Moving electrons create electricity, and electrons flow from the anode, the site of oxidation, to the cathode, the site of reduction. The galvanic or voltaic cell also includes a salt bridge, which helps to balance charge, and lets ions move between the two half cells. In this video, w
