Abstract

The polarography of lead in the iodide medium has shown that an irreversible wave is obtained at moderate concentrations of lead, whereas at high concentrations two waves are obtained and at low concentrations a single reversible wave is obtained. This explains the irreversible waves obtained by the earlier workers who have mainly worked in the region of 0.4mM of lead. From a study of the effect of the head of mercury, temperature, etc. it is shown that the second wave is an adsorption wave resulting from the adsorption of lead iodide complexes at the dropping mercury electrode.
