Which cell will measure standard electrode potential of copper electrode?

A

`Pt(s)|H_(2)(g ,0.1"bar")|H^(+)(aq.,1M)||Cu^(2+)(aq,1M)|Cu`

B

`Pt(s)|H_(2)(g,1"bar")|H^(+)(aq ,1M)||Cu^(1+)(aq,2M)|Cu`

C

`Pt(s)|H_(2)(g ,1"bar")|H^(+)(aq,1M)||Cu^(2+)(aq,1M)|Cu`

D

`Pt(s)|H_(2)(g,1"bar")|H^(+)(aq,1M)||C u^(2+) (aq,1M)|Cu`

Text Solution

Verified by Experts

The correct Answer is:
`Pt(s)|H_(2)(g,0.1"bar")|H^(+)(aq,0.1M)|| Cu^(2+)(aq,1M)|Cu`
Standard electrode potential of copper electrode can be calculated by constructing a concentration cell composed of two half cell reaction in which concentration of species on left h and an right hand side are unity. In such case cell potential is equal to stnadard electrode potential.
