An introductory yet rigorous account of electrolyte solutions which emphasises the connection between the observable macroscopic experimental properties and the interpretations made at the molecular level. * Fully updated and revised including new additional material and worked problems to encourage student understanding * Modern developments in concepts and theory are dealt with in a descriptive manner to promote student awareness of the current state of the subject * Focuses on the physical rather than the mathematical aspects * Emphasises the links between the study of electrolyte solutions and other branches of chemistry, and other scientific disciplines such as biology and biochemistry
