Consider a simple metal ion, Mn+, such that Mn+ + e <---> M
(n-1)+ at E
oM . The complexation of Mn
+ and M
(n-1)+ with x ligands, L, have the following formation constants: Mn
+ + x L <---> MLn
+x for betax;n
andM(n-1)
+ +x L <---> ML
(n-1)+x for beta
x;n-1. The standard potential for the resulting complex, E
oM L , applies to MLn
+ x + e <---> ML
(n-1)+x .
The relative magnitude of the formation constants determine whether E
oM or
E
oM L is greater and whether the complexed species is easier or harder to reduce than the free metal ion.
(a) Find the potential and write the Nernst equation for FeL
n+x + Fe
2+<--> FeL
(n-1)+x + Fe
3+.this problem is so confusing , i just dont know even what to do
