Hi I have measured the corrosion experiment which is shown below. The experiment shows that the Zre values are going in a negative direction. What is the possible reason for this?. Kindly someone help me.
If your Zre values are negative right from the beginning of the experiment, it might indicate an issue with the experimental setup or the measurement equipment. I aam hoping no Incorrect calibration! chek the following!!
few potential causes:
1. Polarity reversal - your connections is reversed -->correctly identify and connect the working electrode, counter electrode, and reference electrode.
2. Check Setting --> If your electrochemical cell and electrodes are set up correctly, the issue might be with the potentiostat or impedance analyzer. Make sure the equipment is functioning correctly and that the settings are appropriate for your experiment. For example, make sure the frequency range, AC voltage, and DC bias are correctly set
Where are the high frequencies? Close to zero? In that case, there should be a bad connection or bad setup of the equipment (which equipment are you using?). If, on the contrary, the values are approaching zero as the frequency decreases, then it may be a feature of the electrochemical system itself (as it happens in some batteries), but, in this case, for lower frequencies you should obtain increasing positive values of Zre.
