This chapter widens the meaning of oxidation and reduction step by step: first as gain or loss of oxygen and hydrogen, then as loss or gain of electrons, and finally as a rise or fall in oxidation number. With oxidation numbers in hand it sorts redox reactions into four types, balances redox equations by two methods, explains redox titrations, and ends with redox couples, the Daniell cell and the standard electrode potential series.
Also called: oxidation and reduction · oxidation number · balancing redox equations
