HYDROLYSIS OF UREA HYDROCHLORIDE. 135 



In the case of acetone-water mixtures the value of H is 

 approximately proportional to the number of molecules of 

 water in the solution, the acetone apparently having no 

 hydrolytic effect.

These results indicate that in the mixtures investigated, 

 whereas the hydrolytic power of alcohol is approximately 

 the same as that of water, acetone appears to have no 

 effect on the degree of hydrolysis of urea hydrochloride.
