I would like to know the potential of two electrode.

1- The first is the electrode of Ag/Ag+ in a saturated solution of NaCl

I think that the pKs of AgCL is 9.8 (is it right?)

So

E= E0+0.06log[(Ks)1/2]

E=0.8-0.506

E=0.506 vs ENH

Is it correct? (in a book I found a value of 0.2 so...)

2- The second is the electrode of Ag/Ag+ in a solution of NaCl at 3 mol/L this time

so

E=E0+0.06logKs-0.06log[Cl+] ??

E=0.8-0.588-0.0286=0.183 V vs ENH

Is it correct?

Thank you for your help
