pH measurement in non-aqueous (ethanol based) media. How do I calibrate the pH-meter?

28 February 2020 0 10K Report

I need to measure the pH (instrumental pH) of some ethanol-based solutions (99 vol.% of ethanol), containing a small portion of HCl 1M. How would you advice to perform the calibration of the electrode (LiCl electrode)? current procedure uses the standards aqueous buffers.

How could I correlate the instrumental pH with the so-called proton activity for that solvent?

References (books- papers...) are very welcome!
