Determining oxidation numbers in hydrogen peroxide, H2O2, and oxygen difluoride, OF2 is the focus of this video presented by Sal Khan. [4:10]

Using water as an example this video module explores how oxidation numbers are assigned. Also explained is the concept of oxidation states with one elements being oxidized and the other being reduced. Trends of oxidization states are...

Study redox reactions in this video. Several examples of reactions are given showing how to determine a compound's oxidation state and whether it was reduced or oxidized. Also students will understand how to determine whether the...

A follow up to an error made in a previous video( Khan Academy: Chemistry: More on Oxidation States) where the oxidation state of oxygen in hydrogen peroxide was shown incorrectly. This video explains the correct oxidation state for...
