What does it mean to calculate hardness in terms of ppm of calcium

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… WebReduce the temperature of your hot water to 60 degrees. Put a steel scale collector in your kettle.
