摘要：
The potentiometric and conductometric titration was used to study complexation between some metal ions and 3-(4-bromophenylazo)pentane-2,4-dione (L) in aqueous ethanol. The standard thermodynamic characteristics of the complex formation reaction were determined. The effective atomic charges in the tautomeric forms of L (azo enol, azo keto, hydrazo) were calculated by MO LCAO quantum-chemical method in the Huckel approximation.
