The formation and stability of 2-aminophenol-4-sulfonic acid-copper (II) complex
Fahiman Edgü,Emre Dölen,Mürşit Pekin
The stability constants of the complex which was formed by 2-aminophenol-4-sulfonic acid and copper (II) were determined potentionmetrically for various ionic strengths, by using CALVIN-BJERRRUM and IRVINROSSOTTI methods, in this work. The acid constants of the ligand were found as pK1=9.193±0.251 and pK2=11.366±0.061 at 20ºC. the overall protonation constants of the ligand were found as logβ2=21.5 for I=0.11 and logβ2=20.0 for I=0.11 and logβ2=16.1 for I=0.06 at 20ºC.
