Nadawa chelation

Chelation wani tsari ne wanda ion ta tsakiya ke ɗaure zuwa biyu ko fiye da atom ɗin daidaitawa na ligand iri ɗaya. A sakamakon chelation, cations scaling (kamar Ca2 +, Mg2 +) suna amsawa tare da jami'an chelating don samar da tsayayyen chelates, wanda ke hana su tuntuɓar anions masu laushi (kamar CO32 -, SO42 -, PO43 - da sio32 -). don haka yana rage yiwuwar ƙima. Chelation shine stoichiometric, alal misali, daurin kwayoyin EDTA zuwa ion karfe mai ban mamaki.
