Textbook Question
Chapter 8, Problem 130AE
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 ΔH for the reaction (in the gas phase)
H2CO3 → CO2 + H2O
Specify a possible cause for the instability of carbonic acid.
