Question
Four successive members of the first series of the transition metals are listed below. For which one of them the standard potential (E0M2+/M) value has a positive sign?
Options
A.Fe (Z = 26)
B.Co (Z = 27)
C.Ni (Z = 28)
D.Cu (Z = 29)
Solution
E0Cu2+/Cu = 0.34 volt
Fe, Co, Ni are below hydrogen in ECS and show less tendency of reduction than hydrogen
