(%ntisti|) for % frag. LESSON XX.—{Continued.)466. Ammonia.—Moisten some freshly-burned quick-lime with a little water. The lime will crumble topowder, or, in other words, become slacked. Mix equalparts of this slacked lime and sal-ammoniac. Put themixture into a small retort, and apply heat. A pungentodor will be recognizable ; from the evolution of am-monia in the form of gas. Ammonia being greedily ab-sorbed by water, forming liquor ammonise or hartshorn,cannot be collected over that liquid. If desired quitefree from admixture with atmospheric air, it must becollected in a pneumatic-trough which contains mercuryinstead of water. For our purpose, however, it willsuffice to collect it by way of displacement. Being asomewhat light gas, however, the delivery tube mustpoint upward, thus, We may easily know when the. • bottle is filled by bringing near to its mouth a glass rod,dipped in hydrochloric acid (spirit of salt, or muriaticacid), when dense fumes of sal-ammoniac will appear;or a slip of originally blue litmus-paper, reddened bythe fumes of hydrochloric acid.* Collect several bottlesfull of this gas, closing them either by stoppers or glassvalves. 467. Invert a bottle over water, and agitate. Remarkhow the water rises. If the bottle were originally quitefilled with ammonia, it will become now quite full ofwater ; and the solution will be hartshorn. * Alkalies turn this paper blue.
