The possibility of using a calomel electrode as a reference standard in the polarographic comparisons in acetonitrile has been studied. The results indicate that the time required for attaining a constant potential is too long to be convenient for such use.
The behaviour of some organic nitrocompounds at the dropping mercury electrode in acetonitrile containing 0.1 molar tetrabutylammonium iodide has been studied. The nitroanilines and the nitrophenols give distinct double waves on polarographic reduction. There is no formation of any maxima in the case of the nitroanilines, whereas, maxima are found to develop with time in the case of the nitrophenols. The maxima are found to be non-suppressible.
The ease of reduction of the nitrophenols and the nitroanilines, as given by their half-wave potentials, is in agreement with the order expected on the basis of the previously established theories of Shikata and Astle. A possible mechanism of the reduction is given with the irreversibility of the reduction in view. / Science, Faculty of / Chemistry, Department of / Graduate
