What is the significance of the Ilkovic Equation ?

Ilkovic equation is a relation used in polarography relating the diffusion current (id) and the concentration of the non-polarisable electrode, i.e., the substance reduced or oxidised at the dropping mercury electrode (polarisable electrode). The Ilkovic Equation holds good for the ‘drop-time’ to vary between 2 to 8 seconds. In order to accomplish this aim and objective the following two critical adjustments may be done carefully:
 Length of capillary
 Manouvering the Hg-pressure to bring the drop time very much within the range
(i.e., 2-8 sec)
