Acid? 
Salts. 
Appearance of the precipitate before the 
nitric acid is applied. 
Arsenites. 
Amorphous. 
Carbonates. 
Amorphous or granular; becoming 
crystalline.

From concentrated solutions, in 
prisms.

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. 
* With concentrated solutions of these salts barium chloride will give a slowly 
formed crystal deposit. 
* Concentrated nitric acid precipitates barium nitrate in large colorless, iso- 
pietric crystals,
