So, should I consider the Ksp values of the interfering ions with Ag+ and CrO42-
Then the nitrate ion won't interfere since it is highly soluble and will stay in solution. However, the Ksp of S2- and Br- with Ag+ is less than the Ksp of the silver chromate reaction. Does this mean that these...
S.C.E: 1/2Hg2Cl2 (s) + e-⇌Hg(l)+Cl-
Emeas=0.242V-0.05916*log[Cl-]
Note: the half cell rxn in the original post should be
Ag2CrO4 (s) + 2e- = 2 Ag(s) + CrO4 2- (aq)
I don't see how the reference electrode matters in this case, since the interfering ions are in the other half cell.
Homework Statement
The electrochemical cell:
SCE // CrO4 2- (x M) / Ag2CrO4 (s) / Ag (s)
is used for the determination of CrO4 2- . The standard reduction potential for the reaction:
Ag2CrO4 (s) + e = 2 Ag + CrO42-
is +0.446 V vs. NHE.
(b) Which of the...
