NITRE. i ^ trated ™ a § nefia ; 



L Nitrate of magnelia. 



It is found in the mother water of nitre, and, 

 like it, very rarely found in mineral waters ; it 

 has an acrid and very bitter tafte ; it imbibes 

 moifture from the air. 



A. a. The magnefian bafis is detected by the 

 fame means, and with the fame appearances, as 

 (page 55, a.) 



b. By lime water, the nitrous acid uniting 

 with the lime, the magnefia is precipitated in a 

 white flaky appearance. The cauftic, vegetable, 

 foOile, or volatile alkali being added, the fame • 

 appearances are produced, the water becomes 

 turbid, and white flakes appear, as defcribed 

 (page 56, b.) The cauftic alkali, uniting with 

 the nitrous acid, precipitates the magnefia. 



c. So alfo, when employed in their mild ftate, 

 the fame appearance will take place, as defcribed, 

 (page 56, A. c.) 



d. With the addition of foap, white flakes 

 appear, as defcribed above, the nitrous acid com- 

 bining with the alkali of the foap, and the mag- 

 nefia with the oil.
