Principles and Applications of Aquatic Chemistry, Second Edition presents the fundamentals of aquatic chemistry through the powerful application of the tableau system. The tableau method elegantly bridges analytical and numerical techniques, enabling users to deftly navigate questions in aquatic chemistry. Starting with a new introductory chapter and a full color interior, the text has been streamlined and includes new coverage of ocean acidification, advances in dissolution kinetics, bioavailability of trace metals, redox kinetics, and updated thermodynamic data. To further help calculate chemical equilibrium in natural waters, Python programs have been developed for each chapter. Each chapter also includes expanded real-world examples and exercises, with a solutions manual available to qualified instructors. Accessible to those with diverse backgrounds in the sciences and engineering, this textbook provides a solid foundation for understanding the chemistry of natural waters.
