 INTRODUCTION. 



CHAPTEE I. THE IDEAL SOLUTION. 



? 1. General nature of the ideal solution. 



§ 2. Equilibrium between gaseous and liquid phases, 

 (a) Vapour pressure at a constant temperature. {J>) Isothermal distillation, (c) Boilins; 

 point of an ideal solution. 



§ 3. Equilibrium between the ideal solution and pure solids, 

 (a) Isothermal relations. (6) Relation between the temperature of fusion and the composi- 

 tion of the solution. 



§ 4. Equilibrium between the ideal solution and the ideal solid solution, 

 (a) Isothermal relations. (6) Relation between the temperature and tlie composition of the 

 two phases. 



CHAPTER II. QUASI-IDEAL SOLUTIONS WITH ONE A.SSOCIATED 



COMPONENT. 

 ^ 1. Associated liquids, 

 (a) Homogeneous equlibrium. [b) Vapour tension of an associated liquid, (c) Acetaldehyde 

 and paraldehyde, {d) Physical properties of associated liquids. 



§ 2. Quasi- ideal solution with a normal and an associated component,
