9922 J. P. Cooke—Solubility of Chloride of Silver in Water. 
A few drops of hydrochloric acid added to the wash-water — 
greatly diminishes its solvent action on flaky chloride of silver, 
but does not wholly prevent it, as is evident from the fact shown 
in the table below, that hydrochloric acid does not precipitate — 
chloride of silver from its solution in water nearly as effectually 
as nitrate of silver; and, as is well known, hydrochloric acid 
if in any considerable excess exerts a strong solvent action on 
the solvent. That the action is an example of simple solution 
is shown by the fact that a considerable portion of the chloride 
of silver dissolved in boiling water is deposited when the sol- 
vent cools. his phenomenon is a striking one and can easily 
of silver. It is evident, therefore, that the granular condition 
of chloride of silver is a crystalline condition, and this exper 
ment may elucidate the manner in which the native crystals 
are produced. ; 
e have thus far only spoken of the solubility of chloride 
of silver in boiling water. As is evident from the erystalliza- 
tion just described, the solubility rapidly diminishes as the 
temperature falls; but even at the ordinary temperature the
