We have a polymer solution composed of Polyvinylpyrrolidone (PVP) and ethanol. The solution is quite viscous. We have an Electrochemical workstation available in our lab. Can we measure the electrical conductivity of our solution using any electrochemical technique like EIS or OCP. And what type of electrode assembly we must use (2 electrodes or 3 electrodes).
Thanks
This can be achieved with AC electrochemical impedance spectroscopy
For best solution, read the following article:

Dear Ahmed,
your, quite viscous, solution is 'quite non-conductive', also.
However, Z-spectra measured from new, high quality, EIS-systems, using the
1) high(er) Freq., F, (F>1kHz), available spectral part,
might be useful for an initial electrochemical characterization, using some
2) big(ger, possible, surface) Area, A, (A>>1 cm2), and a low(er, possible) distance, L, (L
