It is sparingly dissolved by water, but freely by alcohol, ether, and Glacial Acetic Acid, insoluble in glycerine. Specific gravity 1.071. It coagulates albumen. A slip of deal dipped into it, and afterwards into Hydrochloric Acid, acquires, on exposure for a short time to the air, a greenish-blue colour.

It is not solidified by the cold produced by a mixture of Hydrochloric Acid and Sulphate of Soda.
