I'm having trouble figuring out how to identify which is oxidized and which is reduced. Whats the method to this?

Oxidation is loosing electrons and reduction is gaining electrons.

An easy way to remember is: The LEO goes GER.

LEO: Lose Electrons Oxidation

GER: Gain Electrons Reduction

LEO is oxidized since it loses an electron and reduction is the opposite and an electron is gained.

Another acronym to remember it by is: OIL RIG = Oxidation is the Loss of electrons and Reduction is the Gains of electrons.

I remember oxidation and reduction with OIL RIG (oxidation is loss, reduction is gain). Write out the net equation and it becomes easier to see which elements gained or lost electrons.

I used to get confused because it's sorta counter-intuitive that something being reduced is gaining particles (electrons). It helps me to think of reduction as the charge being reduced though. Since electrons have a negative charge, they lower the charge of whatever they are added to. That thought process helps out my brain in remembering which process is reduction and which is oxidation.

An acronym that I find very useful is as mentioned above, OIL RIG. Oxidation is losing electrons, reduction is gaining electrons.

Basically, you just have to look at the balanced equation to determine the oxidation number. Based on this, you can then use the LEO and OIL RIG rules to determine whether or not the element or compound has been oxidized or reduced in the reaction.

Oxidation is a loss of an electron and reduction is the gain of an electron.

Calculate the oxidation number and then notice which has gained electrons (reduction) and has lost electrons (oxidation).
