Abstract

External magnetic fields (≤ 6 kG) significantly increase yields of I3 and H2 as well as oxidation currents in anodic oxidation of potassium iodide. The Lorentz force on ions in the solution induces convection of solution, resulting in acceleration of the entire reaction rate. This is further confirmed from the observation that reddish-brown streams of I3 in the solution, moving downward at zero field, undergo turbulent motion in magnetic fields.
