Polarographic techniques have been used to investigate the complexing behaviour of chromium (III)‐ethylenediamine‐tartrate in aqueous solution. These complexes are reduced irreversibly at the dropping mercury electrode. The stability constants have been calculated by the method of Sundaresan and Sundaram. The values of the kinetic parameters; standard rate constant (K s ) , transfer coefficient (α) and activation energy (Q) have also been calculated in each case.
