Found inWikipedia, Feb. 20, 2013 (Carbonate. In chemistry, a carbonate is a salt of carbonic acid, characterized by the presence of the carbonate ion, CO₃²⁻. The name may also mean an ester of carbonic acid, an organic compound containing the carbonate group C(=O)(O--)₂.)
Encyc. Britannica online, Feb. 20, 2013 (carbonate, any member of two classes of chemical compounds derived from carbonic acid or carbon dioxide. The inorganic carbonates are salts of carbonic acid (H₂CO₃), containing the carbonate ion, CO²/₃-, and ions of metals such as sodium or calcium. Inorganic carbonates comprise many minerals (see carbonate mineral) and are the principal constituents of limestones and dolomites; they also comprise the hard parts of many marine invertebrates. Organic carbonates are esters; that is, compounds in which the hydrogen atoms of carbonic acid have been replaced by carbon-containing combining groups such as ethyl, C₂H₅.)
Oxysalts, via WWW alonsoformula, Feb. 20, 2013 (They are ionic compounds that we obtain them by replacing the hydrogen in a oxyacid by metal cations. named following the same rules for oxyacids, but changing suffixes. For the low oxidation numbers the suffix is -ITE, and the high oxidation numbers the suffix is -ATE. Anion: CO₃²⁻, Additive names: Trioxidocarbonate(2-), Stoichiometric names: Trioxidocarbonate(2-))
