Audited Supplier The bicarbonate ion is formed when carbonic acid undergoes deprotonation. This polyatomic ion consists of a central carbon atom which is chemically bonded to three oxygen atoms. One of these oxygen atoms is bonded to a hydrogen atom. The negative charge of magnitude -1 is delocalized through the remaining oxygen atoms due to resonance.
When an aqueous solution of K2CO3 (potassium carbonate) is treated with carbon dioxide gas, KHCO3 is formed. The chemical equation for this reaction is given by:
CO2 + K2CO3 + H2O → 2KHCO3
The standard enthalpy of formation for this compound corresponds to -963.2 kilojoules per mole. When heated to 120oC, potassium bicarbonate begins to undergo a decomposition reaction to yield water, carbon dioxide, and potassium carbonate.
