Abstract

The limiting current of the triiodide reduction on a vertical plane electrode in solutions containing excess potassium iodide is calculated by the Karman method for natural-convection conditions. Equations for the average and local limiting currents (which depend on the electrode height), the boundary layer thickness, and the vertical component of the fluid velocity are derived. The average limiting currents, experimentally determined as functions of concentrations of solution components and electrode's height, are compared to calculated values.
