Abstract

The stability constants of lead acetato conplexes were evaluated in various ionic strengths (2.00, 1.00, and 0.75), and at various temperature (15, 20, 25, 30, and $35^{\circ}C$), respectively, by the polarographic and potentiometric method of which Hume and Leden had described. The existence of three complex ions, $PbAc^+$, $PbAc_2$, and $PbAc_3^-$ have been shown in the range of concentration of 0~0.8 mole acetate ion. Referring to values obtained, we have derived the following empirical formula with the stability constant (Kijk), ternperature (Tk) and ionic strength (${\mu}j$). log Kijk = (Ai/${\mu}j^3$+ Bi) / Tk + Ci/${\mu}j^3$ + Di . The deduced and observed stability constants are matched in 5% for the K, and $K_3$, and 20% for the $K_2$.
