]24| COMBINATIONS OP OXIMURIATIC ACID AND METALS, 



Arsenic 2 rp + 33-60 chlorine = areenicane. 



-f 7"30 oxigen = white oxide. 



Antimony 42'5 + 34-60 chlorine = antimonane, 



+ 14-86 sulphur = sulphuret. 



+ 7 '50 oxigen — protoxide. 



Bismuth 6/'5 + 3-4 '20 chlorine = bisrauthane. 



+ 15'0S sulphur = sulphuret. 



+ 7''50 oxigen = oxide. 



7. Cn the Action of muriatic Acid on some Comlinations oj 

 Chlorine and Melals. 



Action of mu- Sir HUMPHRY Davy has pointed out in a great variety of 

 riatic acid on instances the existence of an analogy between chlorine and 

 pou'ais o' oxi- oxigen. He has shown, that the former, united with certain 

 muriatic acid inflammables, constitutes, like the latter, acid compounds; and 

 combined with metals, as it has already been observed, sub- 

 stances similar in many respects to metallic oxides. 



I have kept this analogy in view in my inquiries 5 and, di- 

 rected by it in my experiments, I have obtained some results 

 which appear to me to coincide with it. 



Thus having been led to try the action of muriatic acid on 

 dilferent combinations of the metals and chlorine, I have found 

 many of them capable of uniting with this acid, and of form- 

 ing compounds not dissimilar to some of those consisting of 

 acids and metallic oxides. 



Corrosive sublimate, stannane, cuprane, and the combina- 

 tions of chlorine with antimony, zinc, iead^ and silver are all 

 soluble in different degrees in muriatic acid. 

 Corrosive sub- Corrosive sublimate, which is but sparingly soluble in water, 

 and still more sparingly in the sulphuric and nitric acids, is, I 

 have ascertained, very readily soluble in muriatic acid. 1 cubic 

 inch of the common strong acid takes up about 150 grains of 

 this substance, and when gently heated, a quantity far more 

 considerable, about 1000 grains. The compound thus formed 

 solidifies on cooling into a crystalline fibrous mass, of a pearly 

 and brilliant lustre. It is decomposed by heat, the acid being 

 first expelled ; and when exposed to the atmosphere, it efflo- 

 resces, and appears to lose its acid ; for, afterward analysed, it 

 is found to be pure corrosive sublimate.
