    en.wikipedia.org/wiki/Carbonate_hardness

    3 – meaning the concentration of carbonate expressed as if calcium carbonate were the sole source of carbonate ions. An aqueous solution containing 120 mg NaHCO 3 (baking soda) per litre of water will contain 1.4285 mmol/l of bicarbonate, since the molar mass of baking soda is 84.007 g/mol. This is equivalent in carbonate hardness to a ...

    en.wikipedia.org/wiki/Calcium

    Calcium hydroxide, Ca(OH) 2, is a strong base, though not as strong as the hydroxides of strontium, barium or the alkali metals. [17] All four dihalides of calcium are known. [18] Calcium carbonate (CaCO 3) and calcium sulfate (CaSO 4) are particularly abundant minerals. [19]

  5. Calcium oxide - Wikipedia

    en.wikipedia.org/wiki/Calcium_oxide

    Calcium oxide is usually made by the thermal decomposition of materials, such as limestone or seashells, that contain calcium carbonate (CaCO 3; mineral calcite) in a lime kiln. This is accomplished by heating the material to above 825 °C (1,517 °F), [ 6 ] [ 7 ] a process called calcination or lime-burning , to liberate a molecule of carbon ...
