Limestone is a naturally occuring form of calcium carbonate. It is used as building materials and also for manufacture of other building materials such as portland cement. It is used for the production of quickline and slaked lime which have wide applications in chemical, metallugical and construction industry. The pure CaCO_(3) , called precipitated calcium carbonate, is used extensively as filler, providing bulk to materials such as paint, plastics, printing links and rubber. it is also used in toothpastes, cosmetics and antacids. Quicklime and slaked lime are the cheapest and the most widely used bases for neutralising unwanted acids. Lime is used to neutralise acidic soils. An important application of quicklime is in air pollution control for the removal of SO_(2) in electric power plants. slaked lime is used in the manufature of other alkalis and bleacing powder, in sugar refinig, in tanning hide and in water softening. The drying agent which absorbs CO_(2) and reacts violently with water is
