Can I use Ag as counter electrode instead of Pt. in the anodization process of titanium alloys in the present of H2SO4 as an electrolyte?

I have an alloy from titanium and I want to use the Ag as a counter electrode because the unavailability of Pt electrode in my Lab. I will use one of these electrolytes: (0.15M NH4F + H2SO4) OR...

How can I draw the impedance data taken in account the area of the working electrode?

The obtained data from the potentiostat, which I use (Versastat 4, Princeton research applied), doesn't consider the area of the W.E., (see the sample of my result in the attached image). What is...

Should I use a fresh solution to perform Impedance tests along interval times or using the old solution which the specimen is immersed?

I perform the impedance test at interval times, 24 h, 150 h and 300 h. Between these tests the specimens are immersed in the solution (Ringer's solution) To perform the impedance, Should I use...
