The subject of this book is the treatment of transport phenomena in electrolyte solutions and their natural coupling with ionic reactions. The topic is treated at the level of lectures for 3rd year undergraduate students in physical chemistry. The knowledge in statistical mechanics, hydrodynamics and electrodynamics needed for the understanding of the book as well as the necessary mathematical techniques are introduced in a simple and concise way. Treatment of coupled transport and kinetic processes is introduced with normal modes analysis yielding a clear separation of relaxation and propagative modes. The book is conceived at the level of one-particle hydrodynamic continuity equations. Extensions beyond the ideal multicomponent systems are given at the level of chemical model (CM) and mean spherical approximation (MSA) calculations.
