Oxidation vs Reduction Half Rxn

Postby Abby-Hile-1F » Sun Mar 10, 2019 7:45 pm

How do you determine which half rxn is the oxidation half and which is the reduction half? I always get confused on this.

Oxidation releases electrons (on right side of equation), reduction uses electrons (on left side of equation) in short terms.

Hello,
I always use the term oil rig to help me remember which is oxidation and reduction. Oil= oxidation is losing electrons during the reaction and rig= reduction is gaining electrons. Hope this helped!

Oxidation half reaction is where electrons are being released from the reactant, so the electrons are written on the product side. Reduction half reactions is where electrons are being added to the reactant to form a product, so the electrons are written on the left side.

Oxidation is when the species loses electrons and reduction is when the species gains electrons. You would calculate the charge of the species based on its presence in the compound with known charges of elements. The oxidation would have electrons on the right side and the reduction would have electrons on the left side.

I always use LEO says GER. Losing Electron = Oxidation. Gaining Electron=Reduction.

Oxidation loses electrons and reduction gains electrons.

i just remember that reduction reactions have electrons on the reactant side and it helps because they both start with the letter R

an oxidation reaction when you're writing out the balanced charges and elements should have the electrons on the products side as you are losing the electrons (LEO) and the reduction reaction should have the electrons on the reactant side since they are gaining electrons (GER).
