Chemical Name: Calcium Carbonate
Formula: CaCO3
Molecular weight:100.09
Properties:White fine powder without smell and taste. Its relative density is 2.5-2.7, hardly insoluble in water and enthanol, but soluble in lower density acid.(acetic acid, lower density hydrochloric acid and nitric acid).It is difficult to solubilize in lower density vitriol.
