The book "Inorganic Reactions in Water" offers a comprehensive and detailed analysis of the reactions of elements and their simpler compounds, particularly focusing on inorganic chemistry in aqueous solution. It is structured to provide an easy reference to the reagents involved and emphasizes actual chemical behaviors rather than relying solely on electronic structures and theories. The content is the result of over seven decades of research and provides both a correction and an interpretation of older sources dealing with descriptive aqueous chemistry. Additionally, the book includes new information on the reactions of newly discovered elements as well as current data on chemical equilibria and kinetic aspects that are important for understanding redox and non-redox phenomena in aqueous systems.
