    PREFACE P till about twenty-five years ago, Inorganic Chemistry was based mainly on certain fundamental laws and theories, notably the Laws of the Conservation of Mass and of Energy, the Laws of Chemical Combination, the Atomic Theory, Avo- gadro’s Hypothesis, and the Periodic System of Classifying the Elements. The recent development of the subject is char- acterized by the discovery and applications of certain laws and theories usually associated with Physical Chemistry, more par- ticularly the principles of Chemical Equilibrium (including the Law of Mass Action), the conception of Osmotic Pressure and its application to the determination of Molecular Weights in Solution, and the Electrolytic Dissociation Theory. The newer laws and theories are a necessary supplement to, and extension of the older principles established by the labours of Boyle, Lavoisier, Richter, Dalton, Avogadro and Mendeleeff, but their application to the problems of Inorganic Chemistry has to a large extent revolutionized the study of that subject. It is now generally recognized that the newer views have contributed enormously to the development of chemistry, but in spite of this fact their general adoption into courses of elementary instruction in this country has been very slow. The present book is written throughout from the modern standpoint, and it is hoped that it may contribute in some degree to the wider use of the newer principles at a relatively early stage in chemical courses. Chemistry is an experimental science, and no adequate know- ledge of it can be gained without practical work. The study of
