A carbonate is a salt of carbonic acid, (H 2 CO 3), [2] characterized by the presence of the carbonate ion, a polyatomic ion with the formula CO 2− 3.The word "carbonate" may also refer to a carbonate ester, an organic compound containing the carbonate group O=C(−O−) 2.
The bicarbonate ion carries a negative one formal charge and is an amphiprotic species which has both acidic and basic properties. It is both the conjugate base of carbonic acid H 2 CO 3; and the conjugate acid of CO 2− 3, the carbonate ion, as shown by these equilibrium reactions: CO 2− 3 + 2 H 2 O ⇌ HCO − 3 + H 2 O + OH − ⇌ H 2 CO ...
Each blue halo represents one half of a negative charge. In chemistry, an oxocarbon anion is a negative ion consisting solely of carbon and oxygen atoms, and therefore having the general formula C x O n− y for some integers x, y, and n. The most common oxocarbon anions are carbonate, CO 2− 3, and oxalate, C 2 O 2− 4. There are however a ...
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. With two metals, the number of bonding modes increases because carbonate often serves as a bridging ligand.
Neodymium(III) carbonate is an inorganic compound, a salt, where neodymium is in the +3 oxidation state and the carbonate ion has charge -2. [1] It has a chemical formula of Nd 2 (CO 3) 3. The anhydrous form is purple-red, [2] while the octahydrate is a pink solid. [3] Both of these salts are insoluble in water. [4]
Calcium carbonate is a chemical compound with the chemical formula Ca CO 3. It is a common substance found in rocks as the minerals calcite and aragonite , most notably in chalk and limestone , eggshells , gastropod shells , shellfish skeletons and pearls .
Copper(II) carbonate or cupric carbonate is a chemical compound with formula CuCO 3. At ambient temperatures, it is an ionic solid (a salt) consisting of copper(II) cations Cu 2+ and carbonate anions CO 2− 3. This compound is rarely encountered because it is difficult to prepare [2] and readily reacts with water moisture from the air.
