Calcualte the EMF of the cell at 298K
`Pt|H_(2)(1atm) | NaOH(xM),`
`NaCl(xM) | AgCl(s) | Ag`
`E_(Cl^(-)|AgCl|Ag)^(@)` = +0.222V

A

`1.048 V`

B

`-0.04 V`

C

`-0.604 V`

D

emf depends on x and cannot be determined unless value of x is given

Text Solution

Verified by Experts

The correct Answer is:
C
`(1)/(2)H_(2)+AgCl overset(1e^(-))rarr H^(+)+Ag+Cl^(-)`
`E_("cell")=0.22+(0.059)/(1)"log"(1)/([H^(+)][Cl^(-)])`
