• A basic voltmeter can be used to measure the potential, which can then be compared to a standard reference electrode such as a Saturated Calomel Electrode (SCE) or Silver Silver Chloride (Ag/AgCl) and a cell containing 3M KCl.
  • Another method is to evaluate redox potentials (peak-to-peak separation potential) by performing a experiments using a standard redox probe potassium ferric cyanide [K3Fe(CN)6]
  • Estimating the Ag/AgCl electrode potential by conducting the hydrogen evolution reaction (HER) with a Standard Hydrogen Electrode (SHE) in 1M HCl, (purging the hydrogen gas continuously, at 1 atm pressure)
