Calcium carbonate, commonly known as limestone, stone powder, marble, and calcite, is a compound with a chemical formula of CaCO3, which is alkaline and basically insoluble in water but soluble in acid. It is a common substance on the earth. It exists in aragonite, calcite, chalk, limestone, marble, travertine and other rocks, and is also the main component of animal bones or shells.
