Water hardness usually measures the total concentration of Ca and Mg, the two most prevalent divalent metal ions, although in some geographical locations iron, aluminium, and manganese may also be present at elevated levels. Alkalinity Alkalinity is a measure of the ability of a solution to neutralize acids to the equivalence points of carbonate or bicarbonate. pH pH is a measure of the acidity and the base of a solution in terms of activity of hydrogen (H+).
