Some other substances are needed as well. A few other constituents are carbonate and bicarbonate. These two substances also have a major impact on the stabilization of the pH in the proper range of 8. 1 8. 4. Such stabilization is also called buffering. The total carbonate and bicarbonate concentration is also
