Vs Hg/HgO to vs RHE
Type a value in V vs Hg/HgO to get it in V vs RHE instantly.
0.7262V vs RHE
That is −0.102 V vs SHE, −0.343 V vs SCE and −0.299 V vs Ag/AgCl.
What it means
Where is that on the potential scale?
At 25 °C. Reference potentials shift with temperature and filling solution (Ag/AgCl in 3 M KCl is 0.210 V, saturated 0.197 V); junction potentials add a few mV.
The math
How to convert V vs Hg/HgO to V vs RHE
E(SHE) = E(ref) + E°(ref): SCE +0.241 V, Ag/AgCl +0.197 V, Hg/HgO +0.098 V. E(RHE) = E(SHE) + 0.05916 × pH.
Example: -0.2 V vs Hg/HgO = 0.72624 V vs RHE.
RHE values on this page are for pH 14 (1 M KOH). Other references do not depend on pH.
