C1.2 Limestone

1. Calcium carbonate

   • Decomposed by heating
     • Calcium Oxide
       • Reacts with water
         • Forms Calcium Hydroxide
           • Solution of Calcium Hydroxide in water
             • Limewater
               • Carbon Dioxide test
                 • Turns cloudy
           • Slaked Lime
       • Quicklime
     • Carbon Dioxide
       • Reacts with Calcium Hydroxide
         • Calcium Carbonate
   • Carbonates
     • React with acids
       • Carbon Dioxide
       • Salt
       • Water
