What is an oxidation reaction?

Answer 1

A reaction in which an atom loses 1 or more electrons.

the attachment between atoms resulting in atoms sharing one or more pairs of electrons

Answer 2

Electrons have transferred from one atom to another.

Answer 3

A redox, or reduction-oxidation reaction is one in which the oxidation number of the reactants are changed. To change oxidation number, electrons must either be added to or removed from reactants. However, due to conservation of mass, all the electrons that are removed from one compound or atom must be added to another one. And so the number of electrons lost by one thing is equal to the number of electrons gained by the other.

Oxidation is the loss of electrons.

Reduction is the gain of electrons.

Remember: OIL RIG

Oxidation Is Loss; Reduction is Gain.

The thing that is oxidized loses its electrons. However, the electrons it is losing are being given to something else. And so the thing that loses electrons is called the reducing agent.

The thing that is reduced gains electrons from something else. Those same electrons that it is gaining were taken from something else, and so it is called the oxidizing agent! Yes, it is a bit confusing!

See the Related Questions to the left for more information about redox reactions.

***Another way to remember this is LEO and GER (Loss of Electrons is Oxidation) and (Gain of Electrons is Reduction)

•In Redox reactions, something is oxidized and something is reduced

•The thing that is reduced is the oxidizing agent

•The thing that is oxidized is the reducing agent

•Li+ + Na > Na+ + Li

•

•Cu + Ag+ > Cu+ + Ag

•

•Fe3+ + Al > Al3+ + Fe

•

•In + Sn4+ > In2+ + Sn2+

•

•Cu + O2 > Cu2+ + O2-

•

•H2S + CO2 > CH4 + H2SO4

•

•FeS2 + O2 > FeSO4

•

•Fe2SiO4 + H2O > SiO2 + Fe3O4 + H2

•P + 4H2O > H3PO4 + 5/2 H2

•

•6CO2 + 6H2O >C6H12O6 + 6O2

•

•NH4+ + SO42- > NO3- + H2S

•

•Fe3P + H2O > H3PO3 + Fe2+ + H2

Answer 4

loss of electrons /\

First of it, it has nothing to do with oxygen despite what the term might suggest. In the archaic definition, it used to, but nowadays, Redox (Oxidation Reduction Reaction) only means the exchange of electrons from one molecule, atom, or ion, to another molecule, atom or ion.

Oxidation describes the loss of electrons by a molecule, atom or ion.

Reduction describes the gain of electrons by a molecule, atom or ion.

These reactions mutually occur of course. Whenever there is oxidation there is reduction, and whenever there is reduction there is oxidation.

By the way, if you think the terms are a bit backwards, I agree, but that's Chemistry and human terminology, it's not perfect.

An easy way to remember it is OIL RIG (oxidation is loss, reduction is gain).

Answer 5

Oxidation is the loss of electrons

Reduction is the gaining of electrons

Cu2+ + Ag(s) --> Cu(s) + Ag+1

Oxidation states are on the top of the elements, you can see the changes

2+ 0

Cu2+ --> Cu(s)

0 +1

Ag(s) --> Ag+1

Which is loosing and which is gaining electrons?

+2 -> 0. gain of 2 electrons( 2 negative charge) - Reduction

0 -> +1. Loss of 1 electron (1 negative charge) - Oxidation

The meaning of the Reaction type is that there is a change in Oxidation States as i have shown above, an example of an Oxidation-Reduction equation, and why.

Answer 6

Oxidation is the lose of electron/ proton or gain of oxygen and Reduction is the gain of electron/proton or lose of oxygen.Redox reactions are reactions in which oxidation and reduction take place simultaneuosly.A short cut to remember oxidation and reduction is "OIL RIG" ,oxidation is lose reduction is gain of proton/electron.

A good example is the reaction between hydrogen and fluorineH2 + F2 → 2 HF

We can write this overall reaction as two half-reactions: the oxidation reaction:H2 → 2 H+ + 2 e− (loss of two electron)

and the reduction reaction:F2 + 2 e− → 2 F (gain of two electron)

Answer 7

An oxidation reaction occurs when there is a loss of electrons.

Ex: Zn--> Zn2+ +2e-

Answer 8

In this reaction the oxidation states of involved atoms are changed.

Answer 9

(APEX) A reaction in which an atom has gained 1 or more electron

Answer 10

(APEX) A reaction in which the oxidation state of one element increases and another decreases
