This paper deals with the study of the effect of several proton donors on the electrochemical reduction of various dicarbonyl compounds on a mercury electrode, as well as with the calculation of the rate constants of protonation by such proton donors with respect to that of the HsO+ ion.
The polarographic behaviour at the dme of chromate and dichromate is investigated within the concentration limits 0.2 -2.0 mM. In acid solutions, 2 waves are observed representing the reduction to Cr(III) and Cr(II). In neutral unbuffered solutions, 4 waves are obtained for chromate, whereas dichrom
