Phosphonates are highly water-soluble while the phosphonic acids are only sparingly so. Phosphonates are effective chelating agents. That is, they bind tightly to di- and trivalent metal ions, which is useful in water softening. In this way, they prevent formation of insoluble precipitates (scale).
