I want to convert by CV data from ag/agcl reference to hgo to get exact idea about redox peaks vs each reference
Dear Arfah Khan,
You may want to take a look at the useful instructions presented below:
How to convert a potential collected with reference to Ag/AgCl to Reversible Hydrogen Electrode?
- The general equation for this conversion at any pH using Ag/AgCl reference electrode is:
- E(RHE) = EAg/AgCl + 0.059 pH + EoAg/AgCl
- Where EoAg/AgCl = 0.1976 V at 25oC and E Ag/AgCl is your working potential

Hello, to convert your CV data from an Ag/AgCl reference to an HgO reference, you will need to use a conversion factor that takes into account the difference in electrode potentials between the two reference electrodes.
The electrode potential for an Ag/AgCl electrode is typically around 0.197 V, while the electrode potential for an HgO electrode is around 0.85 V. Therefore, to convert your data from an Ag/AgCl reference to an HgO reference, you will need to add 0.85 - 0.197 = 0.653 V to your data.
For example, if your data point is at 0.5 V with respect to an Ag/AgCl reference, it will be at 0.5 + 0.653 = 1.153 V with respect to an HgO reference.
