Solution: When you put sodium carbonate (Na2CO3) in water it produces 2 sodium ions and one carbonate ion (CO3 with a charge of 2-). Carbonic acid (H2CO3) is a weak acid and doesn't want to break apart. So what happens to the CO3 ion in water is that it picks up one or 2 hydrogen ions to become H2CO3 or HCO3-.
