Think OIL RIG
oxidation is loss, reduction is gain

oxidation is loss, reduction is gain
So then you get things like Zn2+ + 2e- = Zn

Cations are positively charged ions, so they will gain electrons and be reduced (like with the Zn2+). Anions are negatively charged ions, so will loose electrons to become reduced, e.g Cl- = Cl + e-
