Hardness by EDTA Titration

The hardness may range from zero to hundreds of milligrams per litre in terms of calcium carbonate, depending on the source and treatment to which the water has been subjected. Ethylenediamine tetra-acetic acid and its sodium salts (EDTA) form a chelated soluble complex when added to a solution of certain metal cations.

Determination of Total Calcium and Magnesium Ion Concentration

Water hardness is a measure of the amount of hard water cations in water. These hard water cations include calcium, magnesium, iron, zinc and the other polyvalent metal ions. In most water samples, calcium and magnesium are the chief contributors to water hardness. Calcium and magnesium are easily measured by titration with the complexing agent ethylene-diaminetetraacetate (EDTA). The EDTA
