ABSTRACT
This paper describes the conductometric, potentiometric and antimicrobial investigations on few Cu(II)- thiosemicarbazone complexes. Solution studies on the complexes have also been carried out in different micellar systems at 25°C and data have been compared with ethanol- water mixture. Stability constants have been determined in 60% ethanol by pH metric study. The conductometric studies have been carried out in doubly distilled water, Triton X-100 and Brij-35 mediums. Proton ligand stability constant and metal-ligand stability have been determined by pH data. Association constants and formation constants have been computed and different types of stoichiometry [M: L] have been observed for metal-ligand complexes as; 1: 2, 1: 3, 1: 4 etc.
