The permanent hardness of water is determined by the water's concentration of cations with charges greater than or equal to 2+. Usually, the cations have the charge of 2+, i.e., they are divalent. Common cations found in hard water include Ca and Mg , which frequently enter water supplies by leaching from minerals within aquifers. Common calcium-containing minerals are calcite and gypsum. A common magnesium mineral is dolomite (which also contains calcium). Ra…
