Carbonic acid   Listen
adjective
Carbonic  adj.  (Chem.) Of, pertaining to, or obtained from, carbon; as, carbonic oxide.
Carbonic acid (Chem.), an acid HO.CO.OH, 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.

"Carbonic acid" Quotes from Famous Books



... bewildered all day, and when we swept down with the darkness into the Arcadian hamlet of "Wingdam," I resolved to go no farther, and rolled out in a gloomy and dyspeptic state. The effects of a mysterious pie, and some sweetened carbonic acid known to the proprietor of the "Half-Way House" as "lemming sody," still oppressed me. Even the facetiae of the gallant expressman who knew everybody's Christian name along the route, who rained letters, newspapers, and bundles from the top of the stage, whose legs frequently appeared ...

... germs—the first elementary principles of life—whenever inorganic conditions favor, and, assimilating air, water, and other inorganic materials, convert them into organic substances, or such as answer to the conditions of organic life. In doing this, they take up and decompose carbonic acid, retain the carbon, and give off oxygen—a vital process not known to occur in the case of animal life. That their primordial germs, or vital units, are in the earth, as the Bible Genesis declares, is conclusively shown by the experimental processes first successfully entered ...

... diffusivity of heat through water, which was found by J.T. Bottomley to be about 0.002 square centimeter per second. The material diffusivities of gases, according to Loschmidt's experiments, range from 0.98 (the interdiffusivity of carbonic acid and nitrous oxide) to 0.642 (the interdiffusivity of carbonic oxide and hydrogen), while the thermal diffusivities of gases, calculated according to Clausius' and Maxwell's kinetic theory of gases, are 0.089 for carbonic ...

... shape of a conical bullet, and contained three men, a dog or two, and several fowls, together with provisions and instruments. It was air tight, warmed and illuminated with coal gas, and the oxygen for breathing was got from chlorate of potash, while the carbonic acid produced by the lungs and gas-burners was absorbed with caustic potash to keep the air pure. This bullet-car was fired from a colossal cast-iron gun founded in the sand. It was aimed at a point in the sky, the zenith, in fact, where it would strike the moon four days later, that is, ...

... for their surfaces were pitted through unequal corrosion, and minute, sharp points, formed of broken fossil shells, projected from them. It was evident that the corners of the original fragments of chalk had been wholly dissolved, from presenting a large surface to the carbonic acid dissolved in the rain-water and to that generated in soil containing vegetable matter, as well as to the humus-acids. {44} The projecting corners would also, relatively to the other parts, have been embraced by ...
