Аннотация: Complexation of silver with histidine in aqueous solution was studied by potentiometric titration at 25degreesC and at a 0.5 mol/l (potassium nitrate) ionic strength. The existence of conjugate acid-base complex species was established. The equilibrium constants for the formation of the [Ag(HHis)(2)](+), [AgHis], and [AgHis(2)](-) complexes were estimated to be = 3.24 +/- 0.16, = 2.30 +/- 0.22, and = 0.75 +/- 0.19, respectively. The equilibrium formation constant K-2(1) for [Ag(HHis)His] depends on the metal ion concentration. The acidity constant of the protonated [Ag(HHis)](+) complex was found, = 6.93 +/- 0.19.
