==Reactions== Salicylaldoxime is the conjugate acid of a bidentate ligand: 2 HO-C6H4CH=NOH + Cu2+ → Cu(O-C6H4CH=NOH)2 + 2 H+ In highly acidic media, the ligand protonates, and the metal aquo complex and aldoxime are liberated. In this way the ligand is used as a recyclable extractant. It typically forms charge-neutral complexes with divalent metal ions.
