The reactions

By convention, the electrode at which oxidation occurs is known as the anode. The other electrode, where reduction occurs, is known as the cathode. On the Standard Reduction Potential Table that we use this means that the anodes are always located relatively below the cathodes (UCLA). For the purpose of remembering, both oxidation and anode begin with vowels. Reduction and cathode both begin with consonants. The electrons freed at the anode by the oxidation make their way through a conductor to the cathode where they are gained, causing a reduction. Thus in a spontaneous electrochemical process electrons flow from anode to cathode.
