(gcide) | mercury bichloride \mercury bichloride\ n.
the compound (HgCl2) consisting of two atoms of chlorine
united with one atom of mercury. Also called {bichloride of
mercury}, mercuric chloride, corrosive sublimate, and
mercury perchloride. It is used as "a topical antiseptic
and disinfectant for inanimate objects". --Stedman's 25th
[PJC]Corrosive \Cor*ro"sive\ (k?r-r?"s?v), a. [Cf. F. corrosif.]
1. Eating away; having the power of gradually wearing,

2. Having the quality of fretting or vexing.
[1913 Webster]
Care is no cure, but corrosive. --Shak.
[1913 Webster]
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 an acrid, burning taste.
It is a virulent poison, a powerful antiseptic, and an
excellent antisyphilitic; called also {mercuric
bichloride}. It is to be carefully distinguished from
calomel, the mild chloride of mercury.

HgCNO2
(gcide) | fulminate of mercury \ful"mi*nate of mer"cu*ry\, n. (Chem.)
The mercury salt of fulminic acid (Hg(CNO)2), called also
mercury fulminate. It is prepared as gray crystals, and is
used primarily in detonators for detonating high explosives,
such as dynamite or TNT.
[PJC]mercury fulminate \mer"cu*ry ful"mi*nate\, n. (Chem.)
The mercury salt of fulminic acid (Hg(CNO)2), called also
fulminate of mercury. It is an explosive compound prepared
as gray crystals, and is used primarily in detonators for
detonating high explosives, such as dynamite or TNT. It is
sensitive to shock and may be detonated by a blow.

NH2HgCl
(gcide) | Precipitate \Pre*cip"i*tate\, n. [NL. praecipitatum: cf. F.
pr['e]cipit['e].] (Chem.)
An insoluble substance separated from a solution in a
concrete state by the action of some reagent added to the
solution, or of some force, such as heat or cold. The
precipitate may fall to the bottom (whence the name), may be
diffused through the solution, or may float at or near the
surface.
[1913 Webster]
2. atmospheric moisture condensed as rain or snow, etc.; same
as precipitation[5].
[PJC]
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 Chem.)
(a) A heavy white amorphous powder (NH2.HgCl) obtained
by adding ammonia to a solution of mercuric chloride
or corrosive sublimate; -- formerly called also
infusible white precipitate, and now {amido-mercuric
chloride}.
(b) A white crystalline substance obtained by adding a
solution of corrosive sublimate to a solution of sal
ammoniac (ammonium chloride); -- formerly called also
fusible white precipitate.
