Acids and bases are important in numerous chemical processes
that occur around us – from industrial processes to biological
ones, from reactions in the laboratory to those in our environment.
The time required for a metal object immersed in water to
corrode, the ability of an aquatic environment to support fish and
plant life, the fate of pollutants washed out of the air by rain, and
even the rates of reactions that maintain our lives all critically
depend upon the acidity or basicity of solutions.
Indeed, an enormous amount of chemistry can be understood in
terms of acid-base reactions.
