As my teacher told us, oxidation is the gaining of oxygen and reduction is the donation of oxygen. In my reference book there are other definitions of this reaction.

So please give me some alternate definitions and, if possible, explain it.

  • $\begingroup$ In class we used the mnemonic OILRIG - Oxidation Is Loss, Reduction Is Gain (referring to the electron transfers). As one of the answers below suggests, you can also define it in terms of oxidation states which I will leave them to explain. $\endgroup$ – surelyourejoking Sep 14 '14 at 9:38
  • $\begingroup$ @surelyourejoking Do you think, he can understand oxidation state? $\endgroup$ – Freddy Sep 14 '14 at 9:53
  • $\begingroup$ I don't want to be condescending in any way, but I don't think so. It's a bit of an iffy concept to learn, it might be best if a professional teaches it. That being said, I guess this is what stackexchange is for. $\endgroup$ – surelyourejoking Sep 14 '14 at 10:04

    $\begingroup$ It'd be best (for next time) if you explained what the alternative definitions were that were given and what was confusing about them. $\endgroup$ – jonsca Sep 14 '14 at 10:46

redox reaction: The reaction in which oxidation and reduction occurs simentationesly is called redox reaction

There are mainly three different ways of determining oxidation and reduction reaction.

  1. Addition and removal of oxygen and hydrogen [classical concept ]

Addition of oxygen or removal of hydrogen is called oxidation. Addition of hydrogen and removal of oxygen is called reduction.

  1. Electron transfer method [method which you mentioned.]

  2. Oxidation State method [Highly used]

Increase in oxidation state is called oxidation. Decrease in oxidation state is called reduction.

redox reaction: The change in oxidation state of reactant occure in reaction is called redox reaction.

You might learn Oxidation State method in your higher class.
