Chemical Tests for Carbonate

In chemistry, carbonate is an inorganic salt, characterized by the presence of carbonate ion, in which a carbon atom is surrounded by three oxygen atom in a triangular planar manner. Carbonate minerals are found in sedimentary rocks. The most common is calcite, the main component of limestone. Salts of carbonates like sodium carbonate and potassium carbonate are used for cleaning and preservation, as well as for the manufacturing of glass.
