When ammonia is added to the solution, pH is raised to 11. Which half-cell reaction is affected by pH and by how much?

A

`E_(o xi)` will increase by a factor of 0.5 from `E_(o xi)^(@)`

B

`E_(o xi)` will decrease by a factor if 0.65 from `E_(o xi)`

C

`E_(red)` will increase by a factor of 0.65 from `E_(red)^(@)`

D

`E_(red)` will decrease by a factor of 0.65 from of `E_(red)^(@)`

Text Solution

Verified by Experts

on increasing concentration of `NH_3` , the concentration of `H^(+)` ion decreases.
`E_(red)=E_(red)^(@)-(0.0591)/nlog[H^(+)]`
