I used this book as an alternate text for a graduate level course in chemical hydrogeology. This was by far the best textbook I used. The class text and most others that I used were qualitative texts. This book presents a quantitative approach to equilibrium chemistry. This definately helped clear up several topics and is full of plenty of examples. At the end of the chapters there are suggestions for additional reading and many practice problems. The authors present cchemical kinetics, equilibrium, acid-base reactions, coordination chemistry, precipitation and dissolution, and redox reactions. This book is definately helpful as it goes through many problems step-by-step and is very instructive.
