Explain the following in term Oxidation of gain or loss of oxygen with two example.
Oxidation Reaction: It is a chemical reaction in which gain of oxygen or loss of hydrogen takes place.
1) 2Mg (s)+O2(g)` "Heat"/`>2MgO(s)
Here, Magnesium is oxidised to become Magnesium Oxide.
Here, Copper is oxidised to become Copper Oxide
In a chemical reaction, when the oxygen is added to the element to form its respective oxide it is the element being oxidised. Example:
