As a rule, magnesium or calcium is preferable as reducing metal from an economical point of view, although lithium, strontium and barium may also be employed. Calcium possesses a much greater affinity to chlorine and permits to effect the reduction theoretically at about 14000 centigrade although in practice such a high temperature is not permissible owing to the use of steel apparatus.

BASIN: General Information on Hardness

23/4/2007· Hardness generally represents the concentration of calcium (Ca 2+) and magnesium (Mg 2+) ions, because these are the most common polyvalent ions. Other ions, such as iron (Fe 2+ ) and manganese (Mn 2+ ), may also contribute to the hardness of water, but are generally present in much lower concentrations.
