    Mar 28, 2014· Experiment on the analysis of a mixture of carbonate and bicarbonate. As the water flows along, it looses carbon dioxide to the atmosphere and by photosynthesis. After some distance this loss becomes the loss of equilibrium C02 and the deposition of calcium carbonate occurs by a reversal of the first part of the equation under #3 above.

    What are the reactions of sodium carbonate with water? - Quora

    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 …

    Difference Between Carbonate and Bicarbonate .

    Oct 06, 2011· Bicarbonate. • Compounds with carbonate ions are not soluble in water at the room temperature and atmospheric pressure. However, many bicarbonate salts are soluble in water at room temperature. • Carbonate compounds are more stable in nature than the bicarbonate compounds.
