ANALYTICAL EXPERIMENTS ON MURIATIC ACID* CjG

 retort. 



The sublimate was in large portions, the fluid only in the 

 quantity of a few drops. I collected by different processes 

 sufficient of both for examination. 



The sublimate emitted fumes of muriatic acid when ex- Properties of

 acid, dissolved in the water. It was a nonconductor of elec-

 its temperature was about that of boiling water; leaving not

When it was heated in it, it produced an orange coloured 

 liquid, and yellow fumes passed into the neck of the retort, 

 which condensed into a greenish yellow fluid. By repeated-

 it several times in the gas, I rendered it of a bright olive

 were formed.
