Potentiometric investigation of the stability of palladium(II) complex of pralidoxime chloride in aqueous solution
Abstract
The formation of a complex between palladium(II) chloride and pralidoxime chloride (PAM-2Cl) has been studied by means of potentiometric pH measurements. The real stability constant of the complex in aqueous medium of ionic strength 0.3 M (KCl) at 25.0°C was log Ks = 7.29. This value was close to that (log Ks = 7.02) obtained previously by spectrophotometric methods after appropriate correction with respect to the corresponding value of the acidic constant of PAM-2Cl (pKca = 8.05), which was also determined under the same experimental conditions.
