ON THE MURIATIC ACID IN ITS DIFFERENT STATES, ^2$ 



ing properties, as that from the phosphoric sublimate, 



I did not examine them minutely : I contented myself with 



ascertaining, that no substance known to contain oxigen 



could be procured from oximuriatic acid, in this mode of 



operation. 



It has been said, and taken for granted by many che- Oximuriatic 



mists, that, when oximuriatic acid and ammonia act upon ^'^^^ ^"^ ^"^"

each other, water is formed. 1 have scTeral times made water but dry 



the experiment, and I am convinced that this is not the "^"".^' of am-

case. A\hen about 15 or 16 parts of oximuriatic acid gas trogen. 



are mixed with from 40 to 45 parts of ammoniacal gas, there 

 is a condensation of nearly the whole of the acid and al- 

 kaline gasses, and from 5 to 6 parts of nitrogen are pro- 

 duced ; and the result is dry muriate of ammonia. 



Mr. Cruickshank has shown, that oximuriatic acid and Action of oxi- 

 hidrogen, when mixed in proportions nearly equal, pro- 1^^^'^^^^^^|^^^^'^ 

 duce a matter almost entirely condensible by water*; and 

 Messrs. Gay-Lussac and Thenard have stated, that this 

 matter is common muriatic acid gas, and that no water is 

 deposited in the operation. I have made a number of ex- 

 periments on the action of oximuriatic acid gas, and hidro. 

 gen. When these bodies were mixed in equal volumes 

 over water, and introduced into an exhausted vessel and 

 fired by the electric spark, there was always a deposition of 

 a slight vapour, and a condensation of from ~ to ^'^ of the 

 volume; but the gas remaining was muriatic acid gas. I 

 have attempted to make the experiment in a manner still 

 more refined, by drying the oximuriatic acid and the 

 hidrogen by introducing them into vessels containing muriate 

 of lime, and by suffering them to combine at common 

 temperatures ; bat I have never been able to avoid a 

 slight condensation ; though in proportion as the gasses 

 were free from oxigen or water, this condensation di- 

 minished. 



I mixed together sulphuretted hidrogen in a high degree Oximuriatic

 volumes : in this instance the condensation was not -^ ; hidrogen.
