One experiment on the specific gravity of chloroazotic acid gave 

 2*49, and another 2*45, and lead to the same result, — 



fiHBB = 2-49.

Thus the 9 volumes of elementary gases which form chloroazotic 

 acid are condensed into 6 volumes, and one volume of the acid con- 

 tains ird volume of nitrogen, i of oxygen, and -rds of chlorine. The 

 specific gravity of the liquid acid was found to be 1*367 7.

The extreme volatility of chloroazotic acid renders the examina- 

 tion of its chemical reaction extremely difficult, and it can be effected 

 only at very low temperatures. 



With phosphorus, the acid enters into ebullition, and disappears 

 without acting sensibly upon it ; arsenic in powder is acted upon, 

 and yields a white product ; silver in powder occasions deflagration, 

 and the liquid disappears ; gold is rapidly dissolved, but platina is 

 acted upon with more difficulty ; alcohol yields an aithereal odour, 

 analogous to that of nitric aether. 



Chloroazotic acid in the gaseous state appears to have no action 

 on phosphorus at ordinary temperatures ; the latter may be even li- 

 quefied by heat, without producing any more apparent action. 



Pulverized arsenic and antimony burn vividly in the gas ; bismuth 

 is immediately attacked, yielding white vapours, but unaccompanied 

 with light ; potassium is slowly acted upon at common temperatures, 

 but the reaction is violent when heated to its fusing-point ; there 

 occurs sudden increase of temperature, accompanied with vivid light ; 

 gold is acted upon, and a plate of copper, heated to dull redness, 

 burns very vividly ; tin heated nearly to its melting-point, does not 

 appear to be immediately attacked, but in a little time it is tarnished 

 and rendered white ; mercury is immediately acted upon ; one-half 

 of the gas disappears, and the remainder is nitric oxide, entirely 

 absorbable by solution of protosulphate of iron. — Ann. de Ch. et de 

 Phys., Mai 1846.
