Procedure for the experiment is as follows:

(a) Pour the prepared potassium ferricyanide solution in the electrochemical cell .

(b) Immense the reference electrode(Ag/AgCl), counter electrode(Pt wire) and working electrode(GCE/Pt/Au).

(c) Open NOVA 1.11 interface & feed the potential range in the window.

(d) Analyse the CV plot.

(a) Deoxygeante the buffer solution which is to be used in the experiment.

(b) Clean the electrode carefully before performing experiment.

(c) Assemble the cell in deoxygenated solution.

(e) After performing the experiment dispose solution in specified waste container.
