Redox chemistry balanced equations

I See the Saunders Interactive General Chemistry CD-ROM, Screen 21 -3, Balancing Equations for Redox Reactions. 

The usefulness of determining the oxidation number in analytical chemistry is twofold. First, it will help determine if there was a change in oxidation number of a given element in a reaction. This always signals the occurrence of an oxidation-reduction reaction. Thus, it helps tell us whether a reaction is a redox reaction or some other reaction. Second, it will lead to the determination of the number of electrons involved, which will aid in balancing the equation. These latter points will be discussed in later sections. 

As most of us recall from our struggles with balancing redox equations in our beginning chemistry courses, many electron-transfer reactions involve hydrogen ions and hydroxide ions. The standard potentials for these reactions therefore refer to the pH, either 0 or 14, at which the appropriate ion has unit activity. Because multiple numbers of H+ or OH- ions are often involved, the potentials given by the Nernst equation can vary greatly with the pH. 

Inorganic chemistry may be divided into four types of reaction acid/base, precipitation, complexation and redox. It is when considering redox reactions that oxidation numbers are used to greatest advantage. This is particularly true when ensuring that a reaction equation has been properly balanced, i.e. that the same amount of reduction as oxidation has taken place. 

In this chapter, 1 explain redox reactions, go through the balancing of this type of equation, and then show you some applications of redox reactions in an area of chemistry called electrochemistry.

Combustion is a redox reaction. So are respiration, photosynthesis, and many other biochemiccd processes people depend on for life. In this chapter, I explain redox reactions, go through the balancing of this type of equation, cind then show you some applications of redox reactions in an area of chemistry Ccdled electrochemistry. Electrochemistry is an cirea of chemistry in which we use chemical reactions to produce electrons (electricity) or use electrons (electricity) to cause a desired chemical reaction to take place.
