 Explain the following in term Oxidation of gain or loss of oxygen with two example.

Advertisements

Solution 1

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.

2)2Cu(s)+O2(g)`"Heat"/`>2CuO(s)

 Here, Copper is oxidised to become Copper Oxide

Solution 2

In a chemical reaction, when the oxygen is added to the element to form its respective oxide it is the element being oxidised. Example:

4Na(s)+O2(g)2Na2O(s) H2S+O2H2O+SO2

  Is there an error in this question or solution?
