The effect of ionic strength on the complexation of copper (II) with salicylate ion.
The complexation of Cu2+ with the hydrogen salicylate, HL-, ion has been studied, at 25 degrees C, by potentiometric measurements with a glass electrode in NaClO4 media for an ionic strength range from 0.5 to 3 M. The complexes found were CuL, CuL2(2-) and CuHL+. Stability constants, extrapolated to zero ionic strength by using the Specific Interaction Theory were: [formula: see text]
