This book presents new and updated developments in the molecular theory of mixtures and solutions. It is based on the theory of Kirkwood and Buff which was published more than fifty years ago. This theory has been dormant for almost two decades. It has recently become a very powerful and general tool to analyze, study and understand any type of mixtures from the molecular, or the microscopic point of view. The traditional approach to mixture has been, for many years, based on the study of excess thermodynamic quantities. This provides a kind of global information on the system. The new approach provides information on the local properties of the same system. Thus, the new approach supplements and enriches our information on mixtures and solutions.
Summary: It is necessary for biochemistry
Rating: 5
This book is very important and necessary for the chemistry and biochemistry. The special interest presents a new definition of solvation. In the traditional definition one needs to specify the standard state for the solute in the ideal gas and liquid phase. It is the reason of some confusion concerning the "standard state" that exists in the literature. The confusion arises from the fact that the solvation Gibbs energy %26Auml;ìs* is determined experimentally in a similar way as one of the conventional standard Gibbs energy of solvation. The latter does involve a choice of standard state. Moreover in all the conventional processes the standard quantities apply only to very dilute solutions of solute in the system, i.e. it could be studied only in the concentration range when Henry's law is obeyed. This is a very severe restriction on the applicability of the standard quantities. In Ben-Naim's definition of a new process of solvation there is no need to specify any standard state for the solvation. This is quite clear from the definition of the solvation process. In addition the process of Ben-Naim's solvation and the corresponding thermodynamic quantities can be defined for the concentrated solutions and pure liquids.
