Announcing 



Qualitative Chemical 

 Analysis 



By M. C. SNEED, Unieemls of Minnuola 



For the sake of simplifying the ana- 

 lytical methods for the beginner, the 

 scheme of analysis provides only for the . 

 detection of the more common inorganic 

 Ions. The general arrangement of the 

 chapters is, first, a theoretical discussion 

 of underlying principles; second, a dis- 

 cussion of the procedure for the analysis 

 of the ions of a given group; third, ex- 

 periments whose aim is to give the 

 specific chemical properties of each of 

 these ions; fourth, the procedure by 

 which the ions are separated and de- 

 tected. 



For college students who have com- 

 pleted general chemistry.
