OBSERVATIONS ON MURIATIC ACip. 185 



liippofed converfion of muriatic or hyperoxigenized muriatic 



acid into nitrous gas, will not pals tor a decomposition, or a 



tranfmutation, of that refra&ory radical ; and the idea of the 



change of potafh into lime, is as erroneous as fome other late 



aflertions refpecling the decompofition of the alkalis.

it pure, as it has nearly the fame degree of tolubuity m water befeparated, be- 

 as muriate of loda. It is foluble in three parts of cold, and caufe of the little 

 lefs of warm water ; and is {lightly deliquefcent. It is foluble lability, 

 in alcohol ; but this property alone is not fufficient to enable us 

 to obtain it free from the muriate of foda, formed along with it 

 in the entire liquor ; as the latter fait, contrary to the aflertions 

 of all authors, is lbluble in alcohol, and feems to be much more 

 fo, when accompanied by the hyperoxigenized muriate. *Tt Obtained by^ 

 was by taking a large quantity of the entire f'alfr, formed by a[ c y h a ^ Zinfi m 

 fending a current of oxigenized muriatic acid gas through a 

 folution of carbonate of foda, and repeatedly cryftallizing in 

 alcohol, that, with great difficulty, I obtained a little pure hy- 

 peroxigenized muriate of foda. It cryftallizes in cubes, or in 

 rhomboids little different from cubes. It produces a fenfation 

 of cold in the mouth ; and its tafie is eafily diftingiiifhed from 

 muriate of foda. It is decompofed by heat, by combuftible 

 bodies, and by acids, in the fame manner as the former fpecies; 

 and the acid holds its place for foda, as for potafh, immediately 

 before the benzoic. The bafis is feparated by potafh only*
