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 PbI 3 were found to be 54 and 9.2 × 10 −9 , respectively. The formation constant of PbNO 3 + was calculated to be 4.6 from the different formation constant of PbI + in perchlorate and nitrate media.
