Automatic and coulometric titrations in studies of chemical kinetics

Abstract

The rate constants for the disproportionations of uranium(V) in perchlorate solutions having hydrogen-ion concentrations between 0.01 and 1.9 M have been evaluated by adding a solution of chromium(II) at a constant rate to one of uranium (VI), employing a vibrating dropping mercury electrode to follow the variation of the concentration of either uranium(VI) or uranium(V). The resulting values are in acceptable agreement with those obtained by other techniques.
