A standard solution of EDTA is prepared, and by titration each ml is found to complex with the Mg in 10.0ml of a solution containing 0.300g of MgCl₂ per liter. A 100 ml pipetful of a certain well water is found to require 8.60 ml of the standard EDTA. (With the knowledge that the conventional method of expressing water hardness in terms of ppm of CaCO3 regardless of the nature of the Carbons and anions actually present, what is the hardness of the well water?
