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). See more In organic chemistry, phosphonates or phosphonic acids are organophosphorus compounds containing C−PO(OR)2 groups (where R = alkyl, aryl, or just hydrogen). Phosphonic acids, typically handled as salts, are generally See more Several methods exist for the preparation of phosphonic acids and their salts. From phosphonic acid Most processes begin with phosphorous acid (aka … See more Hydrolysis Phosphonate esters are generally susceptible to hydrolysis under both acidic and basic … See more Phosphonates are one of the three sources of phosphate intake in biological cells.
