Which ions does the disodium salt of 1-hydroxyethylidene-1,1-diphosphonic acid (HEDP·Na2) act upon?
HEDP·Na₂ (disodium salt of 1-hydroxyethylidene-1,1-diphosphonic acid) acts upon a broad range of metal ions, with a particularly strong affinity for calcium. Primary Target Ions Calcium (Ca²⁺): This is the ion HEDP·Na₂ most notably targets. It forms stable six-membered ring chelates with calcium ions in water systems, which is the basis for its excellent scale inhibition…
