I'm just so confused with the whole reduction and oxidation stuff and the reducing agent and oxidizing agent also. Can anyone explain how to figure them out as simple as they can??
theyre very confusing!

i know some nmeumonics my prof. gave me like:
LEO GER (Losing Electrons is Oxidizing and Gaining Electrons is Reducing..."leo the lion says ger" haha)
and OIL RIG (Oxidation is Losing and Reduction is Gaining)
i just can't get the concept stuck on my head

Redox is so fun!
3 things to remember!
1. KOHES
K - balance KEY elements (this means ignore any elements that do not change as a reactant to product)
O - balance any OXYGEN (if there are 2 oxygen in the right side, add water 2(H2O) on the left.
H - balance the HYDROGEN (if there is water(H2O) or hydroxide (OH), add H+ on the other side)
E - balance the equation by adding ELECTRONS
S - don't forget the STATES!
2nd thing to remember is:
ALWAYS USE YOUR ELECTROCHEMICAL SERIES TABLE!
it helps you A LOT!
3rd - the word OILRIG - Oxidation Is Loss, Reduction Is Gain!
ok.. now you have these 3 points in your head it's gonna be sooooo much simpler!
In a redox reaction.. there's always an oxidant and reductant (different from Oxidation and Reduction!)
By viewing you Electrochemical Series Table... On the left side of the table... the STRONGEST OXIDANT is the top of the table and the WEAKEST OXIDANT is at the bottom.
The STRONGEST REDUCTANT is at the BOTTOM of the table and the WEAKEST REDUCTAND is at the TOP!
now, refering to OIL RIG... you will get a little confuse by the similarity of words. E.g: Oxidation and Oxidant!
Ok.. oxiDANT is the metal in the electrochemical series table! oxiDATION is the process of oxidation!
the trickiest bit tho.. is that the strongest oxiDANT undergoes reducTION and the strongest reducTANT undergoes oxiDATION!
hope this helps u understand.. it sure helped me!

i learned it the easy way, remember the word Oxidation has letter 'o' in it so say that 'o' stands for loss of electrons..
and reduction is the opposite means it is the gain of electrons... so now the element which looses electrons is getting oxidated and the one gaining gets reducted... i hope you understood......

redox reactions are reactions where oxidation and reduction take place simaltaneously
non metals (cations) undergo reduction i,e. either the addition of H or proton (+ve) charge. since they undergo reduction they are good oxidising agents
metals or anions undergo oxidation i.e. either addition of O or (-ve charge) they r reducing agents
