Web1.1 This automated method is applicable to drinking, surface, and saline waters. The applicable range is 10 to 400 mg/L as CaCO 3 . Approximately 12 samples per hour can … Webother ions causing hardness and thus hardness of water is equated to [Ca2+] + [Mg2+]. Water hardness is usually ex-pressed as the milligrams of CaCO 3 equivalent to the total amount of Ca2+ and Mg2+ present in one liter of water. In the determination of water hardness, ethylene-diaminetetraacetic acid (EDTA) is used as the titrant that
WebDetermination of Hardness: Hardness is expressed as mg/L CaCO 3. ... Therefore the total hardness of water can be determination by edta titration method. which is the end point. The analogous result for a complexation titration shows the change in pM, where M is the metal ion, as a function of the volume of EDTA.
