Hello everyone,
I'm actually trying to define the potential of my Pt pseudo electrode but I'm not sure of my protocol
First I suppose that we need to know what kind of reaction is occurring near the reference electrode.
Second I have to find the value of couple vs SHE
Third, apply PH to get the value Vs RHE;
The medium is NaNO3 dissolved into water with C= 100mM, CE, and WE are both gold-based.
My first guess is :
Pt Pt2+ + 2 e- (E°= +1.188 vs SHE)
E = 1,188 - 0,059 PH = 0,775 vs RHE
But I feel skeptical about this.
Can somebody enlighten me?
Thanks.
