Carbonates are readily decomposed by acids. Group 1: Alkali Metals and Carbonates (X 2 CO 3) is the reaction between Li, Na, K, Rb and Cs with CO 3. Orthocarbonic acid is energetically much less stable than orthosilicic acid and cannot exist under normal conditions because of energetically unfavorable orbital configuration of a single central carbon atom bound to four oxygen atoms.[1]:287[3]. As in the case of the isoelectronic nitrate ion, the symmetry can be achieved by a resonance among three structures: This resonance can be summarized by a model with fractional bonds and delocalized charges: Metal carbonates generally decompose on heating, liberating carbon dioxide from the long term carbon cycle to the short term carbon cycle and leaving behind an oxide of the metal. All of these carbonates are white solids, and the oxides that are produced are also white solids. It has a molecular mass of 60.01 g/mol and carries a total formal charge of −2. When pH is too high, the concentration of hydrogen ions in the blood is too low, so the kidneys excrete bicarbonate (HCO−3). Chemical Characteristics: Low solubility in water. In the case of metal ions with insoluble carbonates, such as CaCO3, formation of insoluble compounds results. The metals of group 1, magnesium, calcium, strontium, and barium also form hydrogen carbonates —compounds that contain the hydrogen carbonate anion, HCO − 3 HCO 3 −, also known as the bicarbonate anion.
