If a spoon of copper metal is placed in ...

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
`E_(Cu^(2+)//Cu)^(0)=0.34,E_(Fe^(2+)//Fe)^(0)=0.044"volt"` So Cu can't displace `Fe^(2+)`
