Question
Which is/are correct among the following ?
Given, the half cell emf′s EoCu+2|Cu = 0.337, EoCu+1|Cu = 0.521
Given, the half cell emf′s EoCu+2|Cu = 0.337, EoCu+1|Cu = 0.521
Options
A.Cu+1 disproportionates
B.Cu and Cu2+ comproportionates.
C.EoCu | Cu+2 + EoCu+1 | Cu is positive
D.All of these
Solution
2Cu+1 → Cu + Cu+2
2Cu+1 + 2e → 2Cu
Cu - 2e → Cu+2
_______________
2Cu+1 → Cu+2 + Cu
_______________
∴ Eo
= 0.184
2Cu+1 + 2e → 2Cu
Cu - 2e → Cu+2
_______________
2Cu+1 → Cu+2 + Cu
_______________
∴ Eo
= 0.184Create a free account to view solution
