Polarographic studies of Ni (II) -3-hydroxy-3-phenyl-1-p-sulfonato (sodium salt) phenyltriazene (HPST) and Ni (II) 3-hydroxy-3-p-tolyl-1-p-sulfonato (sodium salt) phenyltriazene (HTST) have been done in aqueous medium. The study deals with influence of methyl group at para position of the present compounds, upon the stabilities of the metal chelates formed by them. Both systems are reversible and diffusion controlled in nature.
