OF DILUTE ALCOHOLIC SOLUTIONS. 15 



Benzene and Ethyl benzoate. 



Benzene: ^1=0.9924. 



1. It is shown that Arrhenius' formuly, z=A\ B", which 

 gives good results in dilute aqueous solutions also holds good 

 when ethyl alcohol is used as the solvent. 



2. The formula can be applied to the solution of all the 

 substances that I have examined with an error of less than one 

 per cent, at least to 10 volume percentage concentration. Water 

 forms an exception. 



3. When water is the dissolved substance the fornmla can 

 be applied only to very dilute solutions. When the concentration 

 exceeds 3 volume percentage the error amounts to more than 

 one per cent.
