Combined, or impregnated, with nitric acid, or some of its compounds.

es 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.

The act or process of oxidizing nitrogen or its compounds so as to form nitrous or nitric acid.

To combine or impregnate with nitrogen; to convert, by oxidation, into nitrous or nitric acid; to subject to, or produce by, nitrification.

A yellow aromatic liquid (C6H5.NO2), produced by the action of nitric acid on benzene, and called from its odor imitation oil of bitter almonds, or essence of mirbane. It is used in perfumery, and is manufactured in large quantities in the preparation of aniline. Fornerly called also nitrobenzol.

azote still used by French chemists); but it forms many important compounds, as ammonia, nitric acid, the cyanides, etc, and is a constituent of all organized living tissues, animal or vegetable. Symbol N. Atomic weight 14. It was formerly regarded as a permanent noncondensible gas, but was liquefied in 1877 by Caille…

avy 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 i…

Of, pertaining to, or containing, nitric and hydrochloric acids. Nitrohydrochloric acid, a mixture of nitric and hydrochloric acids, usually in the proportion of one part of the former to three of the latter, and remarkable for its solvent action on gold and platinum; -- called also nitromuriatic acid, and aqua regia.…

Of, pertaining to, or composed of, nitric acid and muriatic acid; nitrohydrochloric. See Nitrohydrochloric.

esignating, a complex acid called nitroprussic acid, obtained indirectly by the action of nitric acid on potassium ferrocyanide (yellow prussiate), as a red crystalline unstable substance. It forms salts called nitroprussides, which give a rich purple color with alkaline subphides.

ne of those compounds in which nitrogen has a relatively lower valence as contrasted with nitric compounds. Nitrous acid (Chem.), a hypothetical acid of nitrogen HNO2, not known in the free state, but forming a well known series of salts, viz., the nitrites. -- Nitrous oxide. See Laughing gas.

which the real acids are obtained by dehydration; thus, normal sulphuric acid and normal nitric acid are respectively S(OH)6, and N(OH)5.

an that denoted by the termination -ic; as, nitrous, sulphurous, etc., as contrasted with nitric, sulphuric, etc.

employed in oxidation, or which facilitates or brings about combination with oxygen; as, nitric acid, chlorine, bromine, etc., are strong oxidizers.

-- Passive iron (Chem.), iron which has been subjected to the action of heat, of strong nitric acid, chlorine, etc. It is then not easily acted upon by acids. -- Passive movement (Med.), a movement of a part, in order to exercise it, made without the assistance of the muscles which ordinarily move the part. -- Pass…
