Calcium carbonate (CaCO3) is the calcium salt of carbonic acid which at room temperature appears as a white solid and is created by the reaction H 2 CO 3 + Ca(OH) 2 = CaCO 3 + H 2 O; it is the main component of marble. When heated or placed in contact with acid substances, it behaves like other carbonates, decomposing and releasing carbon dioxide.
