• Amazingly Versatile Uses of Calcium Carbonate

    Calcium carbonate crystals (calcite) have a double refraction property due to which they find applications in optics. In case of whitewashing calcium hydroxide reacts with carbon dioxide in air to form calcium carbonate which forms a thin layer on the walls giving them a gloss.
