Carbon \Car"bon\ (k[aum]r"b[ocr]n), n. [F. carbone, fr. L. carbo coal; cf. Skr. [cced]r[amac] to cook.] (Chem.) An elementary substance, not metallic in its nature, which is present in all organic compounds. Atomic weight 11.97. Symbol C. it is combustible, and forms the base of lampblack and charcoal, and enters largely into mineral coals. In its pure crystallized state it constitutes the diamond, the hardest of known substances, occuring in monometric crystals like the octahedron, etc. Another modification is graphite, or blacklead, and in this it is soft, and occurs in hexagonal prisms or tables. When united with oxygen it forms carbon dioxide, commonly called carbonic acid, or carbonic oxide, according to the proportions of the oxygen; when united with hydrogen, it forms various compounds called hydrocarbons. Compare {Diamond}, and {Graphite}. {Carbon compounds}, {Compounds of carbon} (Chem.), those compounds consisting largely of carbon, commonly produced by animals and plants, and hence called organic compounds, though their synthesis may be effected in many cases in the laboratory. The formation of the compounds of carbon is not dependent upon the life process. --I. Remsen {Carbon dioxide}, {Carbon monoxide}. (Chem.) See under {Carbonic}. {Carbon light} (Elec.), an extremely brilliant electric light produced by passing a galvanic current through two carbon points kept constantly with their apexes neary in contact. {Carbon point} (Elec.), a small cylinder or bit of gas carbon moved forward by clockwork so that, as it is burned away by the electric current, it shall constantly maintain its proper relation to the opposing point. {Carbon tissue}, paper coated with gelatine and pigment, used in the autotype process of photography. --Abney. {Gas carbon}, a compact variety of carbon obtained as an incrustation on the interior of gas retorts, and used for the manufacture of the carbon rods of pencils for the voltaic, arc, and for the plates of voltaic batteries, etc. | |

Carbonic \Car*bon"ic\, a. [Cf. F. carbonique. See {Carbon}.] (Chem.) Of, pertaining to, or obtained from, carbon; as, carbonic oxide. {Carbonic acid} (Chem.), an acid {H2CO3}, not existing separately, which, combined with positive or basic atoms or radicals, forms carbonates. In common language the term is very generally applied to a compound of carbon and oxygen, {CO2}, more correctly called {carbon dioxide}. It is a colorless, heavy, irrespirable gas, extinguishing flame, and when breathed destroys life. It can be reduced to a liquid and solid form by intense pressure. It is produced in the fermentation of liquors, and by the combustion and decomposition of organic substances, or other substances containing carbon. It is formed in the explosion of fire damp in mines, and is hence called {after damp}; it is also know as {choke damp}, and {mephitic air}. Water will absorb its own volume of it, and more than this under pressure, and in this state becomes the common soda water of the shops, and the carbonated water of natural springs. Combined with lime it constitutes limestone, or common marble and chalk. Plants imbibe it for their nutrition and growth, the carbon being retained and the oxygen given out. {Carbonic oxide} (Chem.), a colorless gas, {CO}, of a light odor, called more correctly {carbon monoxide}. It is almost the only definitely known compound in which carbon seems to be divalent. It is a product of the incomplete combustion of carbon, and is an abundant constituent of water gas. It is fatal to animal life, extinguishes combustion, and burns with a pale blue flame, forming carbon dioxide. | |
