Which among the following vessels is used to store `CuSO_(4)` solution ?
a Zn vessel
[ Given `E_(Zn^(2+)|Zn)^(@)=-0.76V, E_(Cu^(2+)|Cu)^(@)=+0.34V and E_(Ag^(+)|Ag)^(0)=0.80V` ]

Text Solution

Verified by Experts

`Cu^(2+)|Cu` redox couple has a larger standard redustion potential than of `Zn^(2+)|Zn` . So `Cu^(2+)` will be is reduced to Cu by Zn . Hence , Zn vessel connot be used .
