- Department of Chemistry, Ramnarain Ruia College, Bomba.y-400 019 Manuscript recewed 14 February 1980, revised 20 January 1981, accepted 13 April1981 Potentiometric studies have been carried out on metal complexes of Be2+, Y3+, Pr3+, Nd3+. Dy3+, Gd3+ and U\(O^{2+}_2\) with 2-hydroxy-1-naphthalidene-thiosemicarbazone. The proton-ligand dissociation constants (pK1 and pK2) of the reagent and the formation constants of its metal complexes have been determined by Bjerrum's method at 25o ± 0.1o and at an ionic strength O.1M In 75 : 25 percent (v/v) dioxan-water medium. The validity of Born's relation was examined by studying the plot of Z2/r vs log k values of rare earth complexes of the ligand.
