First edition. Berthollet attempted to provide chemistry with an adequate theoretical foundation so that its experimental results could be analyzed on the basis of theoretical first principles. He gave a thorough critique of the contemporary oversimplified concept of the law of chemical affinity, which had not yet been properly examined; Berthollet's main contribution to the development of this concept was his proof that chemical affinity was relative, varying with the physical conditions-quantity, temperature, solubility, pressure, physical state-accompanying a chemical experiment. He introduced the highly important concept of "chemical mass"-relative affinity combined with the mass of reactants in a chemical combination-to give the total force with which a given quantity of a substance reacted with another. He was probably the first chemist to perform an exhaustive investigation of how physical conditions affect chemical reactions, creating a molecular model of matter to explain the effects of temperature and density on chemical reactions.
