Question

In polarography, the DME is usually the indicator electrode of choice. As a potential is applied on the DME, a current develops. Considering the DME and the Ilkovic equation ,where,

id = 607 n D½ m2/3t1/6C

Discuss how a current is developed and under what conditions it is proportional to the concentration of the electroactive species. What parameters must be controlled in the Ilkovic equation so that the diffusion current is proportional to the concentration. What are the advantages and disadvantages of using the DME and what is meant when it is said that the DME becomes polarized? SHOW WORK
