Total hardness or water hardness is defined as the sum of the concentrations of all alkaline earth ions dissolved in an aqueous sample. However, since, strontium and barium ions are contained only in traces and therefore play only a minor role as hardeners, the definition according to the German norm DIN 38409-H 6 was adopted. According to this standard, the hardness is characterized only by the molar concentrations of calcium and magnesium ions in mmol/l.


The term carbonate hardness describes the amount of magnesium and calcium ions for which equivalent molar amounts of hydrogen carbonate are available in the solution.
