| Abstract: | Iodide ion-selective electrode were studied, prepared and applied for the complex formations and solubility product determination. The thermodynamic formation constant of PbI+ and the solubility product of PbI3 were found to be 54 and 9.2 × 10?9, respectively. The formation constant of PbNO3+ was calculated to be 4.6 from the different formation constant of PbI+ in perchlorate and nitrate media. |
