394- SALTS 



in the open air, it is a fine white tasteless pow- 

 der, insoluble in water, and producing no change 

 on vegetable blues. 14-89 grains of this salt, 

 exposed to the greatest heat of the sand bath, 

 gave out water, and lost 0*39 grain of weight. 

 This was water mechanically lodged. The salt 

 is anhydrous, and composed of 



1 atom oxalic acid . 4-5 

 ] atom oxide of bismuth 10 



14--5 



Tartrate, 9. Tartrate of bismuth. Formed in the same 

 way a fine white tasteless insoluble powder. 

 23*7 grains when heated on the sand bath gave 

 out 5'45 grains water : hence, the constituents 

 are 



1 atom tartaric acid . 8-25 

 1 atom oxide of bismuth 10 

 5 atoms water . . 5-625 



23-875 



The salts of bismuth, if any consequences can 

 be drawn from the preceding list, seem in 

 general to contain 2 or 3 atoms of water. Two 

 of the salts, the sulphate and oxalate, are anhy- 

 drous four, the dinitrate, carbonate, arseniate, 

 and chromate, contain 2 atoms two, the nitrate 

 and phosphate, contain 3 atoms, while the tai> 

 trate contains 5 atoms.
