The potential of a silver`//` silver chloride electrode measured with respect to a saturated calomel electrode `(E_(OP)^(@)=0.244 V)` is `0.022 V`. The standard reduction potential of silver`//`silver chloride electrode is:

Options

A. `0.222 V`
B. `0.266 V`
C. `-0.222V`
D. `-0.266 V`

Explanation

`E_(cell)^(@)=E_(OP_("Calomel"))+E_(RP_(Ag//AgCl))^(@)`
`-0.002=-0.244+(E_(RP_(Ag//AgCl))^(@))`
`:. (E_(RP_(Ag//AgCl))^(@))=0.244-0.022=0.22 V`
