The silver salt is by no means insoluble 
in the ammoniacal solution, so that in 
the 
making of the salt by this method a certain separation of the substance is effected. 
If any impurity were presented, it probably would be detected on analysing the acid 
as again separated from the silver salt.

These analyses, as well as those of the acid previous to combination with silver, 
agree with the formula of palmitic acid, C 32 H 32 O 4 , with which substance the melt- 
ing-point of the acid also identifies it. The calculated numbers in parts per cent, of 
the acid and silver salt are —
