The anode is the electrode where oxidation occurs and electrons are lost. The cathode is where reduction takes place and electrons are gained. These reactions don't occur separately; they must work together in a reduction-oxidation reaction.For this next section, let's assume the electrodes are zinc and copper.o determine the voltage of any cell, subtract the electrode potential of the anode from that of the cathode and you get the electrode potential of the cell, or voltage. Eo cell = Eo cathode-Eo anode. Corrosion is when metal is gradually destroyed through chemical reactions, and it is a real problem in our daily lives.
But they do this in a certain way. Electrons repel each other and try to go to a place with fewer electrons. In a battery, the only place to go is to the cathode. But, the electrolyte keeps the electrons from going straight from the anode to the cathode within the battery. When the circuit is closed (a wire connects the cathode and the anode) the electrons will be able to get to the cathode. In the picture above, the electrons go through the wire, lighting the light bulb along the way. This is one way of describing how electrical potential causes electrons to flow through the circuit.
