WebLecture: Reduction-Oxidation (REDOX) Reactions

Kotz and Triechel, Chemistry and Chemical Reactivity Chapter 3: Sections 8-9 .

3.8 Oxidation-Reduction Reactionsl. All oxidation-reduction reactions (redox reactions) involve electron transfers between the reactants to form the new components. While it may seem like the rules for redox reactions and assignment of oxidation numbers are somewhat arbitrary, they are based on the electron configuration and affinity characteristics of the atoms involved in the exchange.

3.9 Classifying Reactions. A reaction occuring in water-based solution is often classified as one (or more!) of four types: precipitation, salt-forming acid/base, gas-forming, or oxidation-reduction (electron transfer). Note the characteristics of each, and that a given reaction may fall into more than one classification category.
