Electrochemical behavior of I-hydroxypyridine-2-thione and its vanadium
complex is studied using polarographic techniques. Polarograms of ligand and that
of the complex is shown with diffusion characteristics of the waves. Cyclic
voltagram of thione is investigated which shows that a reversible oxidation reduction
of one electron process is taking place. PKa of the thione is found to be in close
agreement with the previous findings
