This is the only comprehensive introduction to this central topic and thus a must–have for many chemists, chemical engineers and material scientists. The book describes the behavior of liquids and solutions and their simplest applications in a basic and self–contained way. The author has extensive experience from research in areas where the theoretical concepts of liquids are applied and adopts here a clear, well–structured approach to provide an excellent overview of pure liquids, simple non–electrolyte, electrolyte and polymeric solutions, as well as the most important types of reaction. Suitable as an introductory text as well as on an intermediate level, since the more advanced parts are clearly marked.
