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, we'll talk about oxidation, reduction, cathodes, and anodes. We'll write redox half reactions for the two half cells, which show the gain and loss of electrons.
