Thermodynamic studies on the complexes between transition metal ions and heterocyclic sulphonamides

ABSTRACT

Thermodynamic equilibrium constants have been determined by potentiometric titration at 20 degrees, 30 degrees, 40 degrees and 50 degrees for the reactions of sulfadiazine [1], sulfamerazine [2] and sulfasomidine [3] with Cu[11], Zn[11] Co[11], Ni[11], Mn[11] by the Irving and Rossotti method in 50% ethanol medium in order to compare the relative activities of different temperatures
