Reduction vs. oxidation
How can you tell the difference between what is reduced and what is oxidized? Is it only dependent on proton transfer?

Re: Reduction vs. oxidation
Oxidation means that it lost electrons and reduction means that it gained electrons.
Re: Reduction vs. oxidation
In an equation, you can also look at oxidation numbers. Oxidized elements will have an increased oxidation number in the products. Reduced elements will have a decreased oxidation number.

Re: Reduction vs. oxidation
Oxidation is a loss of electrons, reduction is a gain of electrons (not protons). I usually remember this with the acronym OIL RIG. The only way to tell if something is reduced or oxidized is by looking at the initial and final oxidation numbers of elements in a reaction.

Re: Reduction vs. oxidation
Species that gain electrons are considered reduced, while species that lose electrons are oxidized.

Re: Reduction vs. oxidation
Oxidation is the loss of electrons and reduction is the gain of electrons. You can determine what is being reduced or oxidized is by the change in oxidation numbers of reactants and products.

Re: Reduction vs. oxidation
You can memorize it with the acronym OIL RIG: Oxidation Is Loss (of electrons), Reduction Is Gain (of electrons).

Re: Reduction vs. oxidation
As mentioned before, oxidation is losing electrons while reduction is gaining electrons. You can either memorize "the LEO goes GER" or OIL RIG.

Re: Reduction vs. oxidation
Basically oxidation means it will lose electrons. On the other side, reduction means it gains electrons in the reaction

Re: Reduction vs. oxidation
Oxidation refers to losing electrons, while reduction means gaining electrons. You can tell by comparing the oxidation numbers of the products and reactants.

Re: Reduction vs. oxidation
Reduction and oxidation is how an electron is transferred. The notation taught in LS is OIL RIG.
Oxidation is Loss of electrons
Reduction is Gain of electrons
When something becomes oxidized, the oxidation number becomes more positive. Being reduced means your oxidation number becomes more negative.

Re: Reduction vs. oxidation
One thing my high school teacher taught me to remember oxidation/reduction is L.E.O (loses electrons oxidation) the lion goes G.E.R (gaining electrons reduction)! Hope this helps make memorization easier :)

Re: Reduction vs. oxidation
You can break down the equation you are given into two different equations to determine how the charges on the molecules change.

To add on, you can determine oxidation numbers by using a set of rules. This links provides some helpful information: https://socratic.org/questions/how-do-y ... a-compound

Re: Reduction vs. oxidation
it is actually not only dependent on proton transfer! i believe you are thinking of bronsted-lowry acid and base reaction from 14A.
ReDox rxns depend on the transferring of charges based on electron gains and losses.
LEO says GER!
Lose Electrons: Oxidation
Gain Electrons: Reduction
(fun acronym to remember the basic difference)

Re: Reduction vs. oxidation
reduction: gain of electrons, charge becomes more negative
oxidation: loss of electrons, charge becomes more positive
I don't think it has to do with proton transfer since it has to do with a gain or loss of electrons.

Re: Reduction vs. oxidation
Oxidation is when a compound loses electrons in the reaction. Reduction is when a compound gains electrons . You can memorize this with the acronym LEO the lion says GER. LEO=loss of electrons is oxidation, GER=gain of electrons is reduction.

Re: Reduction vs. oxidation
It is based on electron transfer. I remember it by "OILRIG" Oxidation is losing e- and reduction is gaining e-

Oxidation is when electrons are lost while reduction is when electrons are gained.

Re: Reduction vs. oxidation
Electrons are lost for oxidation and electrons are gained for reduction.

Re: Reduction vs. oxidation
A good saying is LEO says GER: Losing Electron Oxidizing, Gaining Electrons Reduction
Looking at the change in the oxidation numbers helps indicate if it is a reduction or oxidation.

Re: Reduction vs. oxidation
Reduced species are those that gain electrons and oxidized species are those that lose electrons.

Re: Reduction vs. oxidation
Oxidation is losing electrons and reduction is gaining electrons (OIL RIG). If the positive charge decreases, it is being reduced. If the positive charge increases, it is being oxidized.

Re: Reduction vs. oxidation
an oxidized species will have lost electrons (in other words, its oxidation number will increase), and a reduced one will have gained electrons (so the oxidation number decreases and becomes more negative from the negative charge of the electrons)

Re: Reduction vs. oxidation
LEO the lion goes GER. LEO: lose electrons oxidation GER: gain electrons reduction.
The idea is that when an element's oxidation number (number of electrons) goes down, it's reduced. So gaining electrons will reduce the oxidation number.

Re: Reduction vs. oxidation
you can calculate the oxidation numbers of all of the different elements constituting the molecules and if an oxidation number increases, then that atom/molecule is oxidized, and if the oxidation number decreases then that atom/molecule is reduced
