One source of alkalinity is calcium carbonate (CaCO 3), which is dissolved in water flowing through geology that has limestone and/or marble. Limestone is a sedimentary rock formed by the compaction of fossilized coral, shells and bones.he ability to resist changes in pH by neutralizing acids or bases is called buffering. Alkalinity is important to aquatic organisms because it protects them against rapid changes in pH. Alkalinity is especially important in areas where acid rain is a problem.
It most commonly occurs as a crystalline heptahydrate, which readily effloresces to form a white powder, the monohydrate. Pure sodium carbonate is a white, odourless powder that is hygroscopic (absorbs moisture from the air), has an alkaline taste, and forms a strongly alkaline water solution.his type of glass is known as soda lime glass : soda for the sodium carbonate and lime for the calcium carbonate. Soda lime glass has been the most common form of glass for centuries. Sodium carbonate is also used as a relatively strong base in various settings.
