What is the effect in matter in Oxidation?

1 Answer

Oxidation occurs when atoms lose electrons. This will cause the oxidation number of the particle to increase.


Here are some examples of oxidation.

The video below shows the oxidation of magnesium. This can also be called a combustion reaction.

The reaction can be summarized as follows

#2Mg + O_2 -> 2MgO#

In the reaction the magnesium is oxidized and the oxygen is reduced. This causes the magnesium atom to convert to a #Mg^(2+)# ion and the oxygen atoms become #O^(2-)#. This leads to the formation of an ionic compound.

Here is another video which discussed the oxidation-reduction reaction of copper and an aqueous solution of silver nitrate.

Hope this helps!
