302 Speyers — Solubilities of Some Carhon Compounds^ etc. 



For convenience, the values are all multiplied by 1000 before 

 plotting. 



We notice the following : — 



The molecular volumes of the solutes are larger in water 

 than in the other solvents and decrease in the order of methyl 

 alcohol, ethyl alcohol, propyl alcohol, toluene and chloroform, 

 the only exception being perhaps choral hydrate in ethyl 

 alcohol compared to its solution in chloroform. 



The molecular volumes in chloroform show decided constancy 

 for every temperature and concentration observed, and to a 

 lesser extent in toluene. 



In general, the molecular volumes of the solutes decrease as 

 the temperature rises and the concentration increases. The 

 exceptions are urethane and chloral hydrate in chloroform.
