Carbonic acid is a chemical compound with the chemical formula H 2 C O 3. The molecule rapidly converts to water and carbon dioxide in the presence of water. However, in the absence of water, it is quite stable at room temperature .
The anhydrides of some of these acids are oxides of carbon; carbon dioxide, for instance, can be seen as the anhydride of carbonic acid. Some important carbonates are Ag 2 CO 3, BaCO 3, CaCO 3, CdCO 3, Ce 2 (CO 3) 3, CoCO 3, Cs 2 CO 3, CuCO 3, FeCO 3, K 2 CO 3, La 2 (CO 3) 3, Li 2 CO 3, MgCO 3, MnCO 3, (NH 4) 2 CO 3, Na 2 CO 3, NiCO 3, PbCO 3 ...
For organic chemistry, a carbonyl group is a functional group with the formula C=O, composed of a carbon atom double-bonded to an oxygen atom, and it is divalent at the C atom. It is common to several classes of organic compounds (such as aldehydes , ketones and carboxylic acids ), as part of many larger functional groups.
In organic chemistry, a carbonate ester (organic carbonate or organocarbonate) is an ester of carbonic acid. This functional group consists of a carbonyl group flanked by two alkoxy groups. The general structure of these carbonates is R−O−C(=O)−O−R' and they are related to esters ( R−O−C(=O)−R' ), ethers ( R−O−R' ) and also to ...
The latter is consistent with the pK a ’s of carbonic acid: pK 1 = 6.77 and pK 2 = 9.93. To a single metal ion, carbonate is observed to bind in both unidentate (κ 1-) and bidentate (κ 2-) fashions. [5] In the covalent bond classification method, κ 1-carbonate is anX ligand and κ 2-carbonate is an X 2 ligand.
It is the conjugate base of the hydrogencarbonate (bicarbonate) [8] ion, HCO − 3, which is the conjugate base of H 2 CO 3, carbonic acid. The Lewis structure of the carbonate ion has two (long) single bonds to negative oxygen atoms, and one short double bond to a neutral oxygen atom.
A chemical bond is the association of atoms or ions to form molecules, crystals, and other structures. The bond may result from the electrostatic force between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds, or some combination of these effects.
Carbonation is the chemical reaction of carbon dioxide to give carbonates, bicarbonates, and carbonic acid. [1] In chemistry, the term is sometimes used in place of carboxylation, which refers to the formation of carboxylic acids. In inorganic chemistry and geology, carbonation is common.
