THE following form of this experiment differs from that producing blue iodide of starch usually given in text books, and as I am not aware of it being known it may be of interest to those engaged in teaching the subject to which it belongs.doi:10.1038/040417a0MONDYE. FNatureNature...
The pathway leading to radical products (Kolbe electrolysis) and/or cationic intermediates (nonKolbe electrolysis) is determined mainly by the substituents in the α-position of the carboxylic acid and some experimental factors. The electrolysis products of different carboxylates have been compared with...
The fluoride ions prevent the formation of aluminum hydroxide on the anode thus enabling a current to be produced which is a function of the amount of fluoride added. The range of detection for the analyzer is 0.05 to 80 mu g F/sup -/ per liter of air. Potassium iodide is added to ...

A glow discharge passed from a metal anode to the surface of acid and neutral solutions of potassium iodide, oxidizes iodide to iodine and produces hydrogen peroxide. The total oxidation yield has been examined as a function of iodide concentration; it exhibits a maximum at low iodide ...
In the device in the invention, the mixed solution of potassium iodide and potassium hydroxide is used as electrolyte, wherein iodine ions are oxidized at the anode to generate iodate ions, oxygen is reduced at the cathode to generate hydroxyl ions; the liquid generated by electrolysis is ...
of first oxidising agent to be measured. The first oxidising agent is pref. chlorine which is changed into residual iodine by reaction with an excess of potassium iodide, the liberated iodine being electrolysed. Pref. both electrodes are made of the same metal and have equal surface areas; ...
