So at low scan rate, enough time for ions to accumulate(adsorbed) on surface, so can we expect high capacitance at low scan rate? Or opposite is happening?
Faradic reaction means a heterogeneous chemical reaction takes place on the working electrode. An example would make the concept better. The ferro and feri interconversion while you do CV with potassium ferricyanide solution. In electrochemistry electronic exchange happens. And, charge transfer means, the constituent cations and anions undergo transfer from bulk to the electrode surface and vice versa.
Very nice for beginners it very use full
Very well explained.🙂

How can we determine the operating potential window by experimenta? Which techniques? What will be the set up?
From which literature or text you got the image of "low rate limited" , Electrolyte decomposition and pseudocap CVs? Share the DOI of that paper
So at low scan rate, enough time for ions to accumulate(adsorbed) on surface, so can we expect high capacitance at low scan rate? Or opposite is happening?
Yes, at a low scan rate, you are allowing more time for transfers. I will upload more videos for a better understanding of this part.
In faradic systems with which components (or between what ) the faradic charge transfter takes place?
I will put all the necessary links to the description of this video by tomorrow.
What is the actual meaning of this faradic reaction? What kind of "charges are transfered " and is transfered between what??
