Summary

  1. 1.

    The diffusion coefficients and the diffusion current constants of iodobenzene have been determined in aqueous mixtures of ethanol, dioxane and acetone containing 1 M lithium chloride. The diffusion current constant is found to be proportional to the square-root of the diffusion coefficient determined by the diaphragm cell technique and the number of electrons involved in the reduction process is found to be two. The diffusion coefficients determined by the viscosity and conductivity methods do not explain the anomalous variation of the diffusion current constant with solvent concentration noticed in the case of iodobenzene and they lead to erroneous conclusions regarding the reduction mechanism.

  2. 2.

    It has been found that half-wave potential shifts to more negative values with an increase in the concentration of the organic solvent. The values of E3/4-E1/4 have been found to be of the order of 0·09 V in all media indicating the irreversibility of the electrode process. It has been suggested that the polarographic method can be used for the estimation of iodobenzene.
