hite substance, CaOClcalcium hypochlorite. See Hypochlorous acid, under Hypochlorous. -- Mercuric chloride, corrosive sublimate.

of fretting or vexing. Care is no cure, but corrosive. Shak. Corrosive sublimate (Chem.), mercuric chloride, HgCl2; so called because obtained by sublimation, and because of its harsh irritating action on the body tissue. Usually it is in the form of a heavy, transparent, crystalline substance, easily soluble, and of a…

so called from its tendency to form blue compounds; obtained by heating ammonium oxalate, mercuric cyanide, etc. It is obtained in combination, forming an alkaline cyanide when nitrogen or a nitrogenous compound is strongly ignited with carbon and soda or potash. It conducts itself like a member of the halogen group of…

g powder (Chem.) any violently explosive powder, but especially one of the fulminates, as mercuric fulminate.

ree state, but forming a large class of highly explosive salts, the fulminates. Of these, mercuric fulminate, the most common, is used, mixed with niter, to fill percussion caps, charge cartridges, etc. -- Fulminic acid is made by the action of nitric acid on alcohol.

The process or operation of obtaining the mercury, in its fluid form, from mercuric minerals.

To obtain mercury from, as mercuric minerals, which may be done by any application of intense heat that expels the mercury in fumes, which are afterward condensed. [R.]

A compound of naphthalene or its radical with a metallic element; as, mercuric naphthide.

To treat or test, as a liquid, with a solution of mercuric iodide in potassium iodide and potassium hydroxide, which is called Nessler's solution or Nessler's test, and is used to detect the presence of ammonia.

igher grade, as an -ous compound to an -ic compound; as, to oxidize mercurous chloride to mercuric chloride.

meric modification of cyanogen, obtained as a brown or black amorphous residue by heating mercuric cyanide.

d through the solution, or may float at or near the surface. Red precipitate (Old. Chem), mercuric oxide (HgO) a heavy red crystalline powder obtained by heating mercuric nitrate, or by heating mercury in the air. Prepared in the latter manner, it was the precipitate per se of the alchemists. -- White precipitate (Old…

It is employed as a scientific toy. -- Serp…

oxide thrown down. -- Heavy solution (Min.), a liquid of high density, as a solution of mercuric iodide in potassium iodide (called the Sonstadt or Thoulet solution) having a maximum specific gravity of 3.2, or of borotungstate of cadium (Klein solution, specific gravity 3.6), and the like. Such solutions are much us…

A heavy yellow powder, Hg3O2SO4, which consists of a basic mercuric sulphate; -- called also turpeth mineral.

A bright red pigment consisting of mercuric sulphide, obtained either from the mineral cinnabar or artificially. It has a fine red color, and is much used in coloring sealing wax, in printing, etc.
