Pertaining to, or derived from, or containing, phosphorus in a lower state of oxidation than in phosphoric compounds; as, hypophosphoric acid. Hypophosphoric acid (Chem.), an acid, P2H4O6, produced by the slow oxidation of moist phosphorus, and isolated only as a solution in water. It is regarded as a condensation prod…

Pertaining to, or containing, phosphorus in a lower state of oxidation than in phosphoric compounds; as, hypophosphorous acid. Hypophosphorous acid (Chem.) , an acid, H3PO2, whose salts are produced by the action of barium hygrate on phosphorus. It may be obtained from its water solution, by exaporation and freezing, a…

A stone that becomes phosphoric by heat.

Pertaining to lithophosphor; becoming phosphoric by heat.

ing to, or designating, a monobasic acid, HPO3, analogous to nitric acid, and, by heating phosphoric acid, obtained as a crystalline substance, commonly called glacial phosphoric acid.

Pyrophosphoric. [Obs.]

Pertaining to, or designating, an acid, H4P2O7, which is obtained as a white crystalline substance. Its salts are obtained by heating the phosphates.

Of, pertaining to, or designating, a hypothetical sulphacid of phosphorus, analogous to phosphoric acid, and known in its salts.

Of, pertaining to, or designating, a hypothetical acid of phosphorus, analogous to phosphorous acid, and known in its salts.

basic process, used as a fertilizer. It is rich in lime and contains 14 to 20 per cent of phosphoric acid. Called also Thomas slag, phosphatic slag, and odorless phosphate.

und in roundish masses composed of radiating fibers, first discovered near Bologna. It is phosphorescent when calcined. -- Bologna vial, a vial of unannealed glass which will fly into pieces when its surface is scratched by a hard body, as by dropping into it a fragment of flint; whereas a bullet may be dropped into i…

ith painting, to give the appearance of bronze, gold, or other metal, to any surface. -- Phosphor bronze and Silicious or Silicium bronze are made by adding phosphorus and silicon respectively to ordinary bronze, and are characterized by great tenacity.

A hydrous phosphate of iron occurring in yellow radiated tufts. The phosphorus seriously injures it as an iron ore.

lded or forged, is brittle, and sometimes very hard. Besides carbon, it contains sulphur, phosphorus, silica, etc.

A nonphosphorized, nitrogenous substance, obtained from brain and nerve tissue by extraction with boiling alcohol. It is uncertain whether it exists as such in nerve tissue, or is a product of the decomposition of some more complex substance.

A sugarlike body obtained by the decomposition of the nitrogenous non-phosphorized principles of the brain.

Any substance, as bismuth, glass, phosphorous, etc., which in a field of magnetic force is differently affected from the ordinary magnetic bodies, as iron; that is, which tends to take a position at right angles to the lines of magnetic force, and is repelled by either pole of the magnet.

roup; -- so called from the double effect of fire upon it, in fusing it, and rendering it phosphorescent.

A double salt of fluoric and phosphoric acids.

g the appearance and consistency of ice; - - said of certain solid compounds; as, glacial phosphoric or acetic acids. Glacial acid (Chem.), an acid of such strength or purity as to crystallize at an ordinary temperature, in an icelike form; as acetic or carbolic acid. -- Glacial drift (Geol.), earth and rocks which ha…
