A) mol. wt/2
B) mol.wt/3
C) mol. wt/4
D) mol .wt/7
Correct Answer: B
Solution :
In neutral medium \[M{{n}^{+7}}\] oxidation state change into +4 oxidation state, hence equivalent weight of \[C{{u}^{++}}+2{{e}^{-}}\to Cu;\,\,\,\,E_{C{{u}^{++}}/Cu}^{o}=0.\,34\,\,V\,\].You need to login to perform this action.
