The measured e.m.f. at `25^(@)C` for the cell reaction ,
`Zn(S)+Cu^(2+)(1.0 M)to Cu(s) +Zn^(2+) (0.1 M)` is 1.3 volt, Calculate `E^(@)` for the cell reaction.

Text Solution

Verified by Experts

The correct Answer is:
`1.27045V`
`E_(cell)=E_(cell)^(@)-(0.0591)/(n)"log"([Zn^(2+)])/([Cu^(2+)]),1.3=E_(cell)^(@)-(0.0591)/(2)"log"(0.1)/(0.1)" or "E_(cell)^(@)=1.27045V`
