Hardness of Water by EDTA Titration Introduction Water hardness is caused by natural minerals that are dissolved into the water‚ predominantly calcium and magnesium‚ and is measured as the equivalent concentration of calcium carbonate (in milligrams per litre).

Ca2+ and Mg2+ form insoluble salts with soaps causing precipitation of the soap scum. Another effect of hard water is “boiler
