Chapter 19: Oxidation-Reduction Reactions

Introduction

Assigning Oxidation Numbers – Not colorful, but the page offers good practice for assigning oxidation numbers to atoms in compounds.

http://mhchem.org/homework/OxNumTut.html

(Main Idea: You can use rules to assign oxidation numbers.)

Redox Chemistry – introduction to oxidation-reduction reactions, or redox chemistry.

(Main Idea: Oxidation and reduction are paired reactions.)

Oxidation-Reduction Reactions – Funny look at redox reactions explaining the difference between oxidizing agents and reducing agents. (Requires Flash)

http://www.calgaryacademy.com/ICT/rr/redox4.html

(Main Idea: Oxidation occurs when valence electrons are lost; Reduction occurs when valence electrons are gained.)

Oxidation-Reduction Reactions –Step-by-step look at oxidation-reduction reactions.

Oxidation and Reduction Agents

Oxidizing and Reducing Agents – a look at oxidizing and reducing agents, how to determine the agents in a chemical reaction, and some questions to test your knowledge.
