ANALYSIS OF LIMESTONE INTRODUCTION. Limestone is usually described as rock made from calcium carbonate, CaCO 3, but in fact most limestone rock contains significant amounts of magnesium, silicates, manganese, iron, titanium, aluminum, sodium, potassium, sulphur (as sulphides or sulphates) and this experiment, you will analyze a sample of limestone to find how much calcium .

The Solvay process or ammoniasoda process is the major industrial process for the production of sodium carbonate (soda ash, Na 2 CO 3).The ammoniasoda process was developed into its modern form by Ernest Solvay during the 1860s. The ingredients for this are readily available and inexpensive: salt brine (from inland sources or from the sea) and limestone (from quarries).
FIELD: chemistry. SUBSTANCE: invention refers to the method for preparation of ammonium nitrate limestone used in agriculture. The essence of the method lies in that the conversion chalk with moisture less than 1 wt % is mixed with fusion cake or ammonium nitrate concentrated solution in the presence of inhibitor of calcium nitrate forming with following granulation of obtained suspension.

Calcium carbonate (limestone) is heated to form calcium oxide (quicklime) and carbon dioxide: It is an endothermic reaction and the equilibrium lies far to the left at low temperatures. Only at about 1200 K does the partial pressure of carbon dioxide exceed atmospheric pressure and the decomposition proceeds to completion.
