Hardness can be quantified by instrumental analysis. The total water hardness is the sum of the molar concentrations of Ca and Mg , in mol/L or mmol/L units. Although water hardness usually measures only the total concentrations of calcium and magnesium (the two most prevalent divalent metal ions), iron, aluminium, and manganese are also present at elevated levels in some locations. The presence of iron characteristically confers a brownish (rust-like) colour to the calc… WebHard water has over 200ppm. This imperial measure of hard water is also called grain per gallon (gpg). 1 grain is 64.8mg of calcium carbonate per gallon of water (3.79 litres). 1 grain per gallon or 1 degree Clark is roughly equal to 17.1 parts per million.
