This page discusses the various meanings of oxidation and also reduction (redox) in regards to the carry of oxygen, hydrogen, and also electrons. It additionally explains the state oxidizing agent and reducing agent.

You are watching: Which of the following would not be a redox reaction?

Oxidation and also reduction in terms of oxygen transfer

The state oxidation and reduction can be defined in terms of the including or removed oxygen to a compound. When this is not the many robust definition, as questioned below, that is the most basic to remember.

Oxidation and also Reduction v respect come Oxygen Transfer

Oxidation is the gain of oxygen.Reduction is the loss of oxygen.

For example, in the exploit of iron native its ore:


Because both reduction and also oxidation are emerging simultaneously, this is known as a redox reaction.

An oxidizing certified dealer is substance which oxidizes something else. In the above example, the iron(III) oxide is the oxidizing agent. A reducing agent reduces miscellaneous else. In the equation, the carbon monoxide is the reducing agent.

Oxidizing agents give oxygen to one more substance.Reducing agents remove oxygen from another substance.

Oxidation and also reduction in terms of hydrogen transfer

These are old meanings which are no much longer used, other than occasionally in essential ptcouncil.netistry.

For example, ethanol deserve to be oxidized to ethanal:


An oxidizing agent is required to remove the hydrogen from the ethanol. A generally used oxidizing certified dealer is potassium dichromate(VI) equipment acidified with dilute sulfuric acid. Ethanal can likewise be reduced back to ethanol by adding hydrogen. A feasible reducing agent is sodium tetrahydridoborate, NaBH4. Again the equation is too complicated to think about at this point.


Example 1

The equation below shows an evident example the oxygen move in a simple redox reaction:

< CuO + Mg ightarrow Cu + MgO>

Copper(II) oxide and also magnesium oxide are both ionic compounds. If the above is created as an ionic equation, it becomes obvious that the oxide ions space spectator ions. Omitting castle gives:
