ANALYSIS OF A MINERAL WATER. 2^| 



u redder tint than the ochrey powder which the water let fall 

 spontaneously. 



b. The same salt added to some of the mineral water 

 which had been exposed to the atmosphere for some days', 

 and decanted, produced no change in it. 



21. Oxalate of ammonia instantly produced a copious oxalate of am-

white precipitate. 



22. Oxalic acid produced the same. oxalic acid : 



23. A solution of pure ammonia threw down a precipi- pureammonia: 

 tate. 



24. Equal parts of the mineral w^ter and of fresh made lime water: 

 lime water were mixed together, and the precipitate that 



was thrown down was separated and washed. It was dis- 

 solved in muriatic acid, precipitated by subcarbonate of 

 soda, washed, and dried in a low heat. Distilled vinegar 

 dissolved a part of it. A solution of pure potash dissolved 

 the greater part of the remainder, leaving a brown powder. 



25. Acetate of barytes produced no precipitate in the fil- acetate of ba- 

 tered water. rvtes : 



2(3. Muriate of barytes produced no precipitate in 24 muriate of ba- 

 hours. rytes: 



When the saline contents of the water were concentrated 

 by evaporation to one fourth, a slight precipitate formed. 



27. Muriate of strontian produced no precipitate in the muriate of 

 water, either when fresh, or when concentrated as in 26. strontian:

 precipitate in the fresh water. 01 I JOlasn - 



b, In the boiled water this triple salt produced no change. 



33. A portion of the fresh water was boiled in a glass re- Ga s expelled 

 tort, the curved arm of which was placed under an in- y 0l ing 

 verted jar filled with quicksilver. The gas which was thus and tested with 

 collected was tried with nitric aaid, the acid absorbed a part nuric > 

 of it.
