Why is hardness expressed as different measures? When hardness is expressed as 'mg/l as CaCO3', it's calculated as if all the calcium and magnesium were present only as calcium carbonate. Hard water is a mixture of calcium and magnesium, together with bicarbonate, sulphate, chloride, etc. Ca – is calcium, C carbon and O oxygen.

Calcite has a hardness of on the Mohs scale and that makes it suitable as a lowhardness abrasive. Calcium Carbonate as Chalk has been used as a writing tool for over 10,000 years and is a fine, microcrystalline material. As limestone, calcium carbonate is a .
