372 ELEMENTARY CHEMICAL MICROSCOPY 



II. A. No Immediate Precipitate is Obtained with Barium 

 Chloride. 



Acetate. 



Arsenate. 1 Ferrocyanide. 1 



Borate. 1 Iodide. 



Bromide. Nitrate. 



Chlorate. Nitrite. 



Chloride. Oxalate. 1 



Cyanide. 



Cyanate. 



Ferricyanide. 



II. B. i . Barium Chloride gives a Precipitate Soluble in Nitric 

 Acid. 2 



ggUg Appearance of the precipitate before the 



nitric acid is applied. 



Arsenites. Amorphous. 



Carbonates. Amorphous or granular; becoming 



crystalline. 

 Chromates, bichromates. Yellow granular, or crystalline, only 



slowly soluble in nitric acid. 

 Cyanates. From concentrated solutions, in 



prisms. 



Fluorides. Granular, 



lodates. Stars and dendrites. Only slowly 



soluble. 



Phosphates. Amorphous or granular. 



Sulphites. Granular or crystalline. 



Tartrates. Granular. 



II. B. 2. The Precipitate obtained with Barium Chloride is 

 Insoluble in Nitric Acid. 

 Silicon* uoride. 

 Sulphate. 



Chromate, bichromate and iodate precipitates are only 

 slowly soluble in nitric acid. 



1 With concentrated solutions of these salts barium chloride will give a slowly 

 formed crystal deposit. 



2 Concentrated nitric acid precipitates barium nitrate in large colorless, iso- 

 metric crystals.
