If a strip of \(Cu\) metal is placed in a solution of ferrous sulphate
1 Copper will precipitate out
2 Iron will precipitate out
3 Copper will dissolve
4 No reaction will take place
Explanation:
(d)\(Cu + FeS{O_4} \to {\rm{No}}\,\,{\rm{reaction}}\) Because \(Cu\) has \({E^o} = 0.34\) volt and \(Fe\) has \({E^o} = - \,0.44\) volt.
