Determination of Water Hardness using Complexometric …
mccord.cm.utexas.eduTotal water hardness is usually expressed as the milligrams of CaCO3 equivalent to the total amount of calcium and magnesium present in one liter of water (mg/liter, i.e., ppm). Water hardness may range from zero to hundreds of ppm, depending on the source. The classification of degree of water hardness
