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.
2 CO. , soluble in water and very slightly soluble in alcohol. Pure sodium carbonate is a white, odorless powder that absorbs moisture from the air, has an alkaline taste, and forms a strongly alkaline water solution. It is one of the most basic industrial chemicals., is a colorless, transparent crystalline compound commonly called sal soda or washing soda. Because seaweed ashes were an early source of sodium carbonate, it is often called soda ash or, simply, soda. The Solvay process provides most sodium carbonate for industrial use.
