NITRA
NITRA
A powder of ipecac and opium, compounded, in the United States, with sugar of milk, but in England (as formerly in the United States) with sulphate of potash, and in France (as in Dr. Dover's original prescription) with nitrate and sulphate of potash and licorice. It is an anodyne diaphoretic.
NITRA
n.
A mineral occurring in transparent crystals, usually of a white, sometimes of a reddish gray, or lemon-yellow, color; native sodium nitrate. It is used in making nitric acid and for manure. Called also soda niter.
n.
Either one of two pigments (called blue verditer, and green verditer) which are made by treating copper nitrate with calcium carbonate (in the form of lime, whiting, chalk, etc.) They consist of hydrated copper carbonates analogous to the minerals azurite and malachite.
n.
A liquid appearing like a heavy oil, colorless or yellowish, and consisting of a mixture of several glycerin salts of nitric acid, and hence more properly called glycerin nitrate. It is made by the action of nitric acid on glycerin in the presence of sulphuric acid. It is extremely unstable and terribly explosive. A very dilute solution is used in medicine as a neurotic under the name of glonion.
a.
Of, pertaining to, or designating, a complex organic acid produced as a white crystalline substance by the action of nitrous acid on hydroquinone.
v. i.
To become covered with a whitish crust or light crystallization, from a slow chemical change between some of the ingredients of the matter covered and an acid proceeding commonly from an external source; as, the walls of limestone caverns sometimes effloresce with nitrate of calcium in consequence of the action in consequence of nitric acid formed in the atmosphere.
n.
A white crystalline semitransparent salt; potassium nitrate; saltpeter. See Saltpeter.
n.
A salt of nitric acid.
n.
Nitrate of calcium, a substance having a grayish white color, occuring in efforescences on old walls, and in limestone caves, especially where there exists decaying animal matter.
n.
Any one of a series of nitro derivatives of aniline. In general they are yellow crystalline substances.
a.
Combined, or impregnated, with nitric acid, or some of its compounds.
n.
A process of oxidation, in which nitrogenous vegetable and animal matter in the presence of air, moisture, and some basic substances, as lime or alkali carbonate, is converted into nitrates.
n.
A metallic element of the calcium group, always naturally occurring combined, as in the minerals strontianite, celestite, etc. It is isolated as a yellowish metal, somewhat malleable but harder than calcium. It is chiefly employed (as in the nitrate) to color pyrotechnic flames red. Symbol Sr. Atomic weight 87.3.
n.
A substance resembling pyroxylin, obtained by the action of nitric acid on starch; -- called also nitramidin.
n.
Nitrate of magnesium, a saline efflorescence closely resembling nitrate of calcium.
n.
Potassium nitrate; niter; a white crystalline substance, KNO3, having a cooling saline taste, obtained by leaching from certain soils in which it is produced by the process of nitrification (see Nitrification, 2). It is a strong oxidizer, is the chief constituent of gunpowder, and is also used as an antiseptic in curing meat, and in medicine as a diuretic, diaphoretic, and refrigerant.
n.
Lead monoxide; a yellowish red substance, obtained as an amorphous powder, or crystallized in fine scales, by heating lead moderately in a current of air or by calcining lead nitrate or carbonate. It is used in making flint glass, in glazing earthenware, in making red lead minium, etc. Called also massicot.
n.
A nitrate formed from three molecules of nitric acid; also, less properly, applied to certain basic nitrates; as, trisnitrate of bismuth.
n.
A crystalline nitrogenous body closely related to both uric acid and hypoxanthin, present in muscle tissue, and occasionally found in the urine and in some urinary calculi. It is also present in guano. So called from the yellow color of certain of its salts (nitrates).
a.
Prepared with nitrate of silver.
