CHEMICAL ANALYSIS. 



CHAPTER I. 



REAGENTS. 



The following list contains all the reagents used in the 

 various courses of analysis described in this book, arranged 

 in alphabetical order. Most of them can be procured of 

 the druggists, or the dealers in apparatus and chemicals. 



Directions are given here for the preparation of such 

 reagents only as cannot be thus obtained conveniently. 

 The chemical tests to which each reagent should be sub- 

 jected, in order that the analyst may be assured of its 

 purity, and the strength of the solutions to be made, are 

 also given, when it is necessary. Most of this information 

 is taken from the works of Fresenius. 



The new system of nomenclature and the new formulas 

 being adopted in this work, the new name and formula 

 of each reagent are given first, and, for the benefit of 

 those who are less familiar with these, the old name and 

 formula are afterwards enclosed in parentheses, whenever 

 there is any essential difference between the new and the 

 old.
