| | SANTA MARGHERITA - Dictionary - Carbonic maceration |
 | | The secret is called carbonic maceration, also known as aromatic fermentation because it produces a wine which is known for its bouquet. | | | At the end of this period in the tank full of carbon dioxide the grape contains far less acids than before and the malic acid in particular has been consumed. | | | In other terms, maceration occurs even though the grape is still whole. |

| | This quantity of carbonic acid, which is supplied to the atmosphere chiefly by modern industry, may be regarded as completely compensating the quantity of carbonic acid that is consumed in the formation of limestone (or other mineral carbonates) by the weathering or decomposition of silicates. | | | "Carbonic acid is supplied to the atmosphere by the following processes:--(1) volcanic exhalations and geological phenomena connected therewith; (2) combustion of carbonaceous meteorites in the higher regions of the atmosphere; (3) combustion and decay of organic bodies; (4) decomposition of carbonates; (5) liberation of carbonic acid mechanically inclosed in minerals on their fracture or decomposition. | | | The carbonic acid of the air is consumed chiefly by the following processes:--(6) formation of carbonates from silicates on weathering; and (7) the consumption of carbonic acid by vegetative processes. |

| | Re: why does carbonic acid decompose when it is created with acetic acid? |
| | according to the chemical equation the reaction of the acetic acid and calcium carbonate of the egg shell produces calcium acetate and carbonic acid, which then decomposes into water and carbon dioxide. | | | my theory is that the energy given off by the spontaneous reaction of the calcium carbonate and acetic acid is enough to raise the produced carbonic acid to its activation energy for decomposing. | | | Since the solubility of CO is only 1.45 g/L (about 0.03 mol/L) at 25° C, most of the carbonic acid formed by dissolving an eggshell in vinegar will escape into the atmosphere. |

| | In the oxidizing flame, on the contrary, all the carbon which exists in the interior of the flame is oxidized into carbonic acid (CO^{2}) and carbonic oxide (CO), while the blue color of the cone of the flame is caused by the complete combustion of the carbonic oxide. | | | One atom of carbonic acid is expelled, and the residue is carbonate of soda. | | | The carbonate of lime will produce a yellowish flame for a while, until the carbonic acid is driven off, when the red color of the lime may be discerned. |

| | Joseph Louis Gay-Lussac |
| | When a mixture of 50 parts of oxygen and 100 of carbonic oxide (formed by the distillation of oxide of zinc with strongly calcined charcoal) is inflamed, these two gases are destroyed and their place taken by 100 parts of carbonic acid gas. | | | The density of carbonic gas is thus equal to that of carbonic oxide gas plus half the density of oxygen gas; or, conversely, the density of carbonic oxide gas is equal to that of carbonic gas, minus half that of oxygen gas. | | | It is very remarkable to see acids so different from one another neutralise a volume of ammonia gas equal to their own; and from this we may suspect that if all acids and all alkalis could be obtained in the gaseous state, neutrality would result from the combination of equal volumes of acid and alkali. |
