If a spoon of copper metal is placed in a solution of ferrous sulphate .

A

`Cu` will precipitate out

B

iron will precipitate

C

`Cu` and `Fe` will precipitate

D

no reaction will take place

Text Solution

Verified by Experts

The correct Answer is:
D
Reduction potential of `Cu^(2+)` is greater than r.p. of `Fe^(2+)` so it can not dusplace `Fe^(2+)` from `FeSO_(4)`.
