Elements of chemistry ... gentle heat to the bottom of each two gases will be disengaged, andcombining, will form a white cloud with-in the receiver, which will gradually con-dense and cover its surface with solid salammoniac.

In this experiment the ammonia is set free, in consequenceof the decomposition of the muriate by the quicklime, whichcombines with its muriatic acid. The articles used in smelling bottles, and called volatilesalts, hartshorn, <$-c, is a carbonate of ammonia. MURIATE OF BARYTES, 115. 2 eq. Muriatic Acid, 37+ 1 eq. Barytes, 78. 575. This salt is formed by saturating muriatic acid withcarbonate of barytes. For this purpose, either the native orartificial carbonate may be employed. Muriate of barytes crystalizes in four sided tables, andcontains nine parts, or one proportion of water. It is solu-. C3 How may the process of making the muriate of ammonia be illustrated bythe apparatus represented at Fig. 78. What is the composition, and what thecombining proportion, of muriate of barytes ? How is the muriate of barytesprepared ? HYDROSULPHURETS. 317 ble in about two and a half times its weight of water; andis much employed as a re-agent in chemistry. HYDROSULPHURETS. 576. Sulphuretted hydrogen is formed by the action ofmuriatic acid on sulphuret of antimony, or some other me-tallic sulphuret. This gas is capable of forming salts with the alkalies, oralkaline earths, when passed into their aqueous thus performs the office of an acid, and the compounds soformed are called hydrosulphurets. The hydrosulphurets are all of them easily decomposed,with the disengagement of sulphuretted hydrogen ; the fetidodor of which, seldom leaves the experimenter in any doubtconcerning the character of the compound.
