Hardness

Hard water (or water hardness) is a common quality of water which contains dissolved compounds of calcium and magnesium and sometimes other divalent and trivalent metallic elements. The term hardness was originally applied to waters that were hard to wash in referring to the soap wasting properties of hard water.
