ABSTRACT
The main objective of this chapter is to introduce the reader to physical chemistry of electrolyte solutions. An electrolyte solution consists of charged species (ions), and it makes these solutions very useful for electrochemical science and engineering. Concentration, activity, activity coef†cient, and chemical potential of both solute and solvent are described in detail. The concentration of species in weak electrolytes and pH of aqueous solutions are discussed, and physical chemistry of buffer solutions is explained.
