What is oxidation/reduction?
Here
FE+03---->
Oxygen gains electrons but FE looses
Would this be a redox?
Reduction or oxidation?
Please help me understand how i can classify a chemical reaction.

It is a redox reaction, because oxygen is being reduced (gaining electrons) and iron is being oxidised (losing electrons).
Just remember oxidation is loss of electrons / reduction is gain
And redox reactions are when oxidation and reduction both occur within the reaction.

Oxidation is loss of electrons or loss of hydrogen.

could you give me an example of a redox reaction, oxidation reaction and reduction. Thanks

okay so a redox reaction, is when electrons are lost by one reactant, and transferred to another. So:

For example the reaction to make table salt

Na + Cl = NaCl (table salt)

for this reaction to happen Na (being the metal in this reaction) loses an electron and forms a Na+ ion (so we can say it is oxidised) and Cl (being the non-metal in this reaction) gains this electron and forms a Cl- ion (we can say that chlorine is reduced because it has gained an electron). Since both reduction and oxidation have occured we can call this a redox reaction.

We can call the sodium a Reducing agent because it reduces the chlorine, and call chlorine an oxidising agent because it oxidises the sodium

The Na+ and Cl- form ionic bonds as they are electrostatically attracted to each other.

Hope this helps
