Edta titration method for calcium

WebThe other three methods consisted of direct titrations (d) of mangesium with EDTA to the EBT endpoint after calcium had been removed. If desired, calcium could then be estimated by subtracting the magnesium titration (d) from the titration for calcium plus magnesium (a). For removal of calcium, three precipitation procedures were compared. http://hardsoftwater.com/determination-of-hardness-of-water-by-edta-method/
