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 stabilisation is also called buffering.\u003c\/p\u003e\n\u003cp style=\"box-sizing: border-box; margin: 0px 0px 15px; text-align: justify;\"\u003e \u003c\/p\u003e\n\u003cp style=\"box-sizing: border-box; margin: 0px 0px 15px; text-align: justify;\"\u003eThe total carbonate and bicarbonate concentration is also called carbonate alkalinity or carbonate hardness.
