The `E^(@)` for the following cell is +0.34 V. In(s)|In `(OH)_3(aq)"||"Sb_2^(-)(AQ)"|"Sb(s)`.
Using `E^(@)=-1.0 V` for the In `(OH)_3`| In, couple, calculate `E^(@)` for the `Sb_2^(-)`|Sb half-reaction:

A

`-1.34`

B

`+0.66`

C

`+0.82`

D

`-0.66`

Text Solution

Verified by Experts

The correct Answer is:
D

`0.34 = 1 + E_(SbO_(2)^(-) | Sb)^(@)`
`implies E_(SbO_(2)^(-) |Sb)^(@) = 0.34 - 1 = -0.66 V `
