Anode, -, oxidation
Cathode, +, reduction
How I remember which is which:
-Anode: A-Negative-Ode (electrode).
-Because it’s negative, oxidation must occur here (oxidation is an increase in state, like -3 to +3, so electrons are lost from the atom), and with the extra electrons, it’s more negative than the cathode.
-Cathode is opposite of anode, so reduction and positive.
