It dissolves mercuric oxide, giving a mercuric cyanide which may be obtained in white crystals on evaporation.
Mercuric cyanide also gives off all its HCN when distilled with iron filings or zinc dust, sulphuric acid, and water.
The reagent is added till no further precipitate is produced, which is known by filtering a small portion at intervals and testing with the potassio-mercuric iodide to see if finished.
Mercuric cyanide is said to be an irritant poison, and to be similar in its action to corrosive sublimate.
