Electrochemical Impedance spectroscopy study of ferricyanide system using different working electrodes
Procedure:
● Prepare four solutions of potassium ferricyanide solutions having concentrations of 0.01 mM, 0.1 mM, 1 mM, and 10 mM.
● Prepare the solutions in a 100 ml volumetric flask.
● Take 10µl of each solution using a micropipette and place it on a screen-printed electrode.
● Analyze the graph obtained from all four solutions.
● The graph represents the impedance responses of different concentrations of K3Fe(CN)6 in the Nyquist format.
