chemical composition of limestone

Limestone - Formation, Composition, Types and Uses Limestone, or calcium carbonate, is the common rock found throughout the world. Oldest and perhaps slightly overlooked,limestoneis very much part of our everyday life. It may be hidden with your walls, in the water you drink, the food you consume, or in the cosmetics. First discovered
