What is the Difference Between Oxidation and Reduction?
Oxidation and reduction reactions involve an exchange of electrons between reactants. For many students, the confusion occurs when attempting to identify which reactant was oxidized and which reactant was reduced. What is the difference between oxidation and reduction?

The Difference Between Oxidation State and Oxidation Number
Oxidation state and oxidation number are terms often thought to mean the same thing, but mean slightly different things. Find out the difference between oxidation states and oxidation numbers.

What Is Oxidized And What Is Reduced in Oxidation and Reduction Reactions?
In oxidation-reduction or redox reactions, it is important to be able to identify which atoms are being oxidized and which atoms are being reduced. To identify if an atom is either oxidized or reduced, you only have to follow the electrons in the reaction.

Synthesis Reactions
This is an explanation of what synthesis reactions are, plus there are examples of synthesis reactions.

How Many Types of Chemical Reactions Are There?
There is more than one way to classify chemical reactions, so you may be asked to name the 4, 5, or 6 main types of chemical reactions. Here is a look at the main types of chemical reactions, with links to detailed information about the different types.
