612 WILLIAM LAWTON GOODWIN ON THE 
solution of lithium chloride almost as freely as in water, but that the maximum 
point is nearly 10 degrees lower. Beyond the maximum the solubility greater 
is than that of any other solution heretofore examined.

Hydrochloric Acid.—A solution of hydrochloric acid was made, of specific 
gravity 1:046, containing an amount of pure hydrochloric acid per 100 c.c., 
very nearly equivalent to 20 grammes of potassium chloride. In this case the 
wash bottle was filled with the same solution, and the flask was cooled down 
before the stream of chlorine was passed through the solution to be experi- 
mented upon. The numbers below show that chlorine is much more soluble in 
hydrochloric acid solution than in pure water. Of course the results at the 
higher temperatures are only approximate, owing to the continual weakening 
of the solution. Chlorine hydrate appeared at 0°, began to decompose at 2°, 
and had completely disappeared at 7°.
