Balancing Redox Reactions in Acidic or Basic Environments
A well presented overview of the steps followed when balancing redox reactions in either an acidic or a basic environment.


Balancing Redox Reactions Using the Oxidation Number Method
Study sheets, examples, with clearly written explanations on balancing redox reactions in either an acidic or a basic environment.


*Electrochemistry
An extensive set of notes providing an excellent overview of electrochemistry up to the AP level. Lists of questions and exercises are also provided.


*Electrochemistry
Possibly the most comprehensive source of tutorial aide on electrochemistry chemistry you will find on the Web. It includes notes, tutorials, practice problems, and labs.


Electrochemistry: Voltaic & Electrolytic Cells
Covers assigning oxidation numbers, oxidizing and reducing agents, balancing redox reactions, redox titrations, electrochemical and electrolytic cells, and Faraday's Law.


How Batteries Work
A great introduction and overview to batteries, the electrochemistry of how and why they work.


How Solar Cells Work
A great introduction and overview to solar cells, the electrochemistry of how and why they work.


Internet Chemistry - Oxidation-Reduction
Includes basic and extended concepts, exercises and examples.


*Oxidation-Reduction
One of the best websites for a great review of oxidation-reduction. Here you'll find topics covering review of terms, half-reactions, reduction potentials, electrochemical cells, review questions, and tutorials.


*Oxidation-Reduction Equations
A very good introduction into redox reactions, balancing equations, and dealing with organic compounds that undergo redox reactions. Practice problems and solutions are provided.


Reduction Oxidation
PChemTeam developed this tutorial which covers the meaning of redox, rules governing oxidation numbers, and a link to a website that does a great job of covering every aspect of redox reactions.


*Reduction & Oxidation Reactions
Great website. It includes identifying if a redox reaction takes place and how they are different from non-redox reactions, explains how to determine oxidation states of elements, what half reactions are, identifies substances that undergo reduction or oxidation, provides practice in assigning oxidation states, and help balancing redox reactions.
