Calcium carbonate is an inorganic compound, is a compound, neutral, basically insoluble in water, soluble in acid. It is a common material on the earth, exists in aragonite, calcite, chalk, limestone, marble, travertine and other rocks. It is also the main component of animal bones or shells. Calcium carbonate is an important building material, which has a lot of industrial USES. It is also a common reagent in middle and high school chemistry (it is often used to react with hydrochloric acid to form CO, etc.)

Light calcium carbonate: amorphous powder, tasteless, odorless. Slightly hygroscopic, stable in dry air, decomposed in acid. Heavy calcium carbonate: white powder, odorless and tasteless. Stable in air. Almost insoluble in water, slightly soluble in water containing ammonium salts or ferric oxide. In case of dilute acetic acid, dilute hydrochloric acid and other bubbles boil and dissolve, heat and release carbon dioxide and calcium oxide. Its activity is larger than that of common calcium carbonate, and it has a reinforcing property. Active calcium carbonate: it is easy to be dispersed in the adhesive and can improve the reinforcing property.
