Action of Hydrated and Nonhydrated Salts on Saponification.

data in tables 64 and 65 were obtained, using the same salt solutions. 

 It was at this point that we decided to study also methyl formate. 

 For tables 67 and 69 new solutions were used, since those earlier em- 

 ployed had not been preserved. The volumes of the solutions of the 

 salts that contained 30 c.c. of water were calculated as described 

 above, the water per cubic centimeter of the solution being the differ- 

 ence in weight between 1 c.c. of the solution and the salt in 1 c.c. The 

 water used in preparing the solutions of the salts, bases, and acid had 

 been carefully purified, and had a mean specific conductivity of 1.5X 10~ 6 

 at 25. This water was also employed in recrystallizing the salts. In the 

 tables of data the concentrations of the solutions of the salts are ex- 

 pressed as N, N/2, and N/4. Tables 56, 58, 60, 62, and 64 give the 

 percentages of the methyl acetate saponified; tables 65, 67, and 69 of 

 the methyl formate. Duplicate measurements were made with fresh 

 solutions of magnesium sulphate and strontium bromide; since the 

 results obtained with these salts were very low as compared with the 

 results from the other salts that contain a large amount of water of 

 crystallization. The results found were, however, identical with those 

 earlier obtained.
