Question

Statement-1: `E_(cell)^(0)=0` for a chloride ion concentration cell.
Statement-2 : For this concentration cell where `E_(cell)=(RT)/(nF)ln([Cl^(-)]_(LHS))/([Cl^(-)]_(RHS))`

Answer 1

`Pt,Cl_(2)|Cl^(-)(aq)||Cl^(-)(aq)|Cl_(2)(g),Pt`
anode : `2Cl^(-)toCl_(2)+2e^(-)(R.H.S)`
cathode: `Cl_(2)+2e^(-)to2Cl^(-)(L.H.S)`
`E_(cell)=0-(RT)/(nF)ln([Cl^(-)]_(LHS))/([Cl^(-)]_(RHS))`
`E_(cell)=(RT)/(nF)ln([Cl^(-)]_(RHS))/([Cl^(-)]_(LHS))`
