Electrochemistry combustion reactions

In addition, electrochemistry allows the carrying out of a combustion reaction at normal temperatures (cool combustion). The most useful reaction to use for the production of power by electrochemical means is the combustion of hydrogen (discussed later in the section, see page 273) - not only for energetic reasons but also because the product (water) is harmless for man and the environment ... 

Oxidation—reduction reactions, commonly called redox reactions, are an extremely important category of reaction. Redox reactions include combustion, corrosion, respiration, photosynthesis, and the reactions involved in electrochemical cells (batteries). The driving force involved in redox reactions is the exchange of electrons from a more active species to a less active one. You can predict the relative activities from a table of activities or a halfreaction table. Chapter 16 goes into depth about electrochemistry and redox reactions. 

In a general sense, oxidation is a reaction in which a substance (molecule, atom or ion) loses electrons. These are transferred to another substance called - oxidant. The oxidation number of the substance being oxidized increases. Oxidation and reduction always occur simultaneously. In nature, oxidation reactions play an important role, e.g., in - respiration, metabolic processes, photooxidation, - corrosion and combustion, and, most importantly in electrochemistry, oxidation processes proceed at - anodes.

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.
