Problem: Write Lewis structures for CO32-, HCO3-, and H2CO3. When acid is added to an aqueous solution containing carbonate or bicarbonate ions, carbon dioxide gas is formed. We generally say that carbonic acid (H2CO3) is unstable. Use bond energies to estimate ΔE for the reaction (in the gas phase) H2CO3 → CO2 + H2O
