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

 Insoluble in Nitric Acid. 



Silicofluoride. 

 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. .
