High quality Calcium carbonate with cas 471-34-1
Calcium carbonate is also called the limestone, stone powder, is common on earth a chemical,
belongs to the inorganic mineral, alkaline, poorly soluble in water, soluble in acid,
naturally in aragonite and calcite, chalk, limestone, marble, limestone and so on within the rock,
lime rock containing carbon dioxide and water insoluble calcium carbonate function
can be converted to calcium bicarbonate, dissolve with water can also precipitate calcium carbonate,
calcium bicarbonate that's why the formation of karst cave.
