Word Count : 464
The Ilkovic equation is a fundamental relationship in polarography, which is a branch of electro-analytical chemistry involving the measurement of current in an electrochemical cell as a function of applied voltage. It describes the diffusion-controlled current observed at a dropping mercury electrode under conditions of reversible reduction of a metal ion. The equation is expressed as: $I_d = 607 \, n \, D^{1/2} \, m^{2/3} \, t^{1/6} \, C$ In this equation, $I_d$ represents the diffusion current, which is the limiting current observed when the reduction or oxidation process at the electrode surface is entirely controlled by the rate at which the analyte diffuses to the electrode.
