Seashells contain calcium carbonate. The calcium carbonate reacts with the acid in the vinegar and causes carbon dioxide bubbles to form. Even though the acid in vinegar is weak it can, over a period of time, dissolve shells.
As a result, the three calcium carbonate minerals-calcite, aragonite and vaterite-are among the most important rock-forming minerals. Rocks are not the only calcium carbonate deposits in nature, most stretches of water and countless plants and animals contain huge amounts of calcium carbonate.alcium Carbonate. Whole mountain chains are made from Calcium Carbonate in the form of chalk, limestone, marble and dolomite. It constitutes more than 4% of the earthâs crust. In soluble form it is dissolved in rivers and oceans where plants and animals absorb it and use it to build skeletons and shells.
