What is Calcium carbonate CAS 471-34-1？
Calcium carbonate, also known as limestone or stone powder, is a common chemical substance on Earth. It belongs to inorganic salt minerals, is alkaline, difficult to dissolve in water, and easily soluble in acid. It naturally exists in rocks such as aragonite, calcite, chalk, limestone, marble, and limestone. Insoluble calcium carbonate in limestone layers can be converted into calcium bicarbonate by reacting with water containing carbon dioxide. Water containing calcium bicarbonate can also precipitate calcium carbonate, which is the reason for the formation of caves.
