Experimental Determination of the Coefficient in the Steady State Current Equation for Spherical Segment Microelectrodes

Abstract

The coefficient in the steady state current equation for spherical segment microelectrodes has been evaluated experimentally for various values of the height of the spherical segment. For this purpose chronoamperometric reduction of Hg2+2 ion at a silver microdisc electrode in perchloric acid solution has been employed. The diffusion coefficient of Hg2+2 in 0.25 M HC104 at 30 C was determined as .0000112 sq.cm/s. Microelectrodes, Spherical segment electrodes, Steady state, Mercury.
