Oxidation numbers (states)
CHEMISTRY - Secondary 2
In This part we will study:
Calculating the change of the oxidation number in the oxidation-reduction Reaction (redox reaction)
The advantage of using oxidation numbers is that they can help us in determining the type of chemical change occurring to an element during the chemical reaction.
You already know the concepts of the oxidation and reduction, which are:
Oxidation is the process of losing electrons resulting in an increase of the positive charge.
Reduction is the process of gaining electrons resulting in a decrease of the positive charge.
