Reduction vs. oxidation

[Shanzey]

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

[PranaviKolla2B]

Oxidation means that it lost electrons and reduction means that it gained electrons.

[MinuChoi]

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.

[Kylie Lim 4G]

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.

[CalvinTNguyen2D]

Species that gain electrons are considered reduced, while species that lose electrons are oxidized.

[Hannah Pham]

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.

[Jessica Li 4F]

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

[205154661_Dis2J]

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

[Erik Buetow 1F]

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

[Nare Nazaryan 1F]

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

[Emily Burghart 1k]

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.

[Christine Honda 2I]

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 :)

[Marni Kahn 1A]

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

[Robin Cadd 1D]

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.

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

[BeylemZ-1B]

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)

[Alexandra Bartolome 2H]

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.

[EthanPham_1G]

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.

[Kallista McCarty 1C]

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

[Jessica Kwek 4F]

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

[Brandon Valafar]

Electrons are lost for oxidation and electrons are gained for reduction.

[Madelyn Romberg 1H]

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.

[Bryan Chen 1H]

oil rig
oxidation is loss
reduction is gain

[505306205]

Reduced species are those that gain electrons and oxidized species are those that lose electrons.

[Viviana Velasquez]

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.

[Daria MacAuslan 1H]

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)

[Kavya Immadisetty 2B]

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.

[Brandon Valafar]

Oxidation: loses electrons. Reduction: Gains electrons.

[Diana Andrade_4F]

Reduction means gain of electron, it becomes more negative. While oxidation is the loss of electron, becomes more positive.

[Kyle Rex 1K]

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
