At common temperatures, it is but slightly soluble in water; 
it requires 1016 parts of that liquid to dissolve one part of 
phloridzine. 
At 100°, water dissolves its own weight; the solution is 
bottle green, but on cooling assumes a dull white color and 
becomes a solid mass. 
Water, acidulated with sulphuric, nitric, or hydrochloric 
acids, dissolves very little phloridzine, but it becomes very 
soluble on the addition of a few drops of solution of ammonia. 
At the end of twenty-four hours these solutions are of a deep 
yellow, and it is not possible to discover any trace of phlorid- 
zine. 
Alcohol at common temperatures dissolves one half its 
weight, and then, by agitation, forms bubbles like soapy 
water. 
If we pour this solution, drop by drop, into water, the 
phloridzine forms a flocculent precipitate, and to obtain it in 
the crystalline form, must be redissolved and allowed to cool 
slowly. 
At the boiling temperature, alcohol dissolves it in every 
proportion. 
It is almost insoluble in sulphuric ether, either cold or 
boiling; it is very soluble in sulphuric acid of commerce; weak 
nitric acid likewise dissolves it, and becomes of a yellow 
color; weak hydrochloric acid dissolves it very slowly. 
Treated with half its weight of nitric acid, and a suitable 
quantity of water, its properties are totally changed; after an 
hour's boiling the liquid became of a rose color; after twenty- 
four hours of rest, it was a deep red. There was not found 
either on the bottom or sides of the vessel, any trace of 
phloridzine, and the author in vain endeavored to precipitate 
it by an alkali. 
Solution of ammonia dissolves phloridzine without altera- 
tion, and communicates to it a yellow color. 
Potassa and soda dissolve it with the same readiness, but 
the solutions are without color. 
A single drop of ammonia in an ounce of distilled water, is
