      • Limewater
        • tests for carbon dioxide (CO2)
          • Bubble gas through lime water - if cloudy, CO2 is present
      • Used for building material
      • Limestone is heated in a ROTARY LIME KILN
        • Makes cement
          • To make mortar add water and sand
    • Heat
    • Adding water to calcium oxide
