Abstract: The stability constants of 1:1 and 1:2 complexes formed between Cu+2, Ni+2, Cd+2 and UO2+2 with Schiff base derived from condensation. Of benzofuran-2-carbohydrazide with 2-hydroxy-1-napthaldehyde has been determined by pH metric titration method as suggested by Irving-Rossodi [13]. The titrations were carried out at four different ionic strengths viz. 0.05, 0.10, 0.15 and 0.20 M NaClO4 solution in non-aqueous medium 60:40% (v/v) alcohol-water and at constant temperature of 30±1°C.
