Some of the properties of concentrated hydrogen peroxide are summarized. Stability and stabilization of hydrogen peroxide solutions are discussed. Special attention is devoted to the compatibility and explosion hazard of concentrated hydrogen peroxide. Mention is made of the actual and potential uses of this newly available material.

As a sequel to an earlier paper, electron micrographs are shown which demonstrate crystal structure directly in so‐called amorphous carbon blacks. The crystalline particles of such a substance have a smaller mean size than the amorphous particles in the total distribution. The effect of variable particle shape upon such things as mean particle diameter and specific surface calculations is pointed out. It is suggested from all the experimental evidence, including electron and x‐ray diffraction data, that the crystal particles are small graphitic units, and that the graphitic nature of the carbon black is a surface rather than a volume phenomenon. The presence of the crystalline component in a carbon black distribution seems to be an intrinsic property of acetylene black made at high temperature.

Abstract : The thought is developed that a considerable opportunity existed in application of the principles and tools of metallurgy to the study of electroplates. The initial aim, to develop a reason for the cracks in chromium plate, proved to be a fortunate choice, as all of the considerations later developed center around this cracking phenomenon.

A relatively simple potentiostat is described which automatically performs the function of maintaining the potential of a working electrode constant at any predetermined value during the entire course of an electrolysis. The instrument is applicable with applied voltages and currents of any reasonable magnitude. Its component parts are easy to assemble, it does not require preliminary calibration, and its control sensitivity of ±0.015 v. is ample for the great majority of applications of controlled potential electrolysis. The application of controlled potential electrolysis as a convenient separation technic in connection with polarographic determinations of metals is described, and data are presented which demonstrate the utility of the method in the analysis of the Copper Group metals. As an example of the preparation of organic compounds by controlled potential electrolysis, experiments on the selective reduction of 9‐(o‐iodophenyl)‐acridine to 9‐(o‐iodophenyl)‐dihydroacridine are described. The recently developed technic of coulometric analysis with a mercury cathode at controlled potential is described. Data are presented which demonstrate the accuracy of the method for the determination of copper, bismuth, and lead. The application of the technic of coulometric analysis to the determination of the reduction states that correspond to the polarographic waves in complicated reductions at the dropping mercury electrode is discussed.
