While phosphates function to clean and attack the corrosion problem, linear polyphosphates also exhibit the capability to sequester heavy and soft metal ions with a valence of +2, which includes iron, manganese, calcium, and magnesium. Sequestration of iron and manganese cations prevent color formation by binding the +2 cations to prevent their oxidation to colored cations. The binding of calcium and magnesium cations (sequestration) acts to soften the water, also improving water quality.
