Updated and revised, this highly successful text details the basic chemical principles required for modern studies of atmospheres, oceans, and Earth and planetary systems. This completely accessible introduction allows undergraduate and graduate students with little formal training in chemistry to grasp such fundamental concepts as chemical equilibria, chemical thermodynamics, chemical kinetics, solution chemistry, acid and base chemistry, oxidation-reduction reactions, and photochemistry. In the companion volume Introduction to Atmospheric Chemistry (also to be published in May 2000), Peter Hobbs details atmospheric chemistry itself, including its applications to air pollution, acid rain, the ozone hole, and climate change. Together these two books offer an ideal introduction to atmospheric chemistry for a variety of disciplines.
