Electrode potential for Mg electrode var...

Electrode potential for `Mg` electrode varies according to the equation
`E_(Mg^(2+)|Mg)=E_(Mg^(2+)|Mg)^(ϴ) -(0.059)/2 "log" 1/([Mg^(2+)])`
The graph of `E_(Mg^(2+)|Mg) vs log [Mg^(2+)]` is

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
B
(b) `E=E^(@)+(0.059)/(2)"log"[Mg^(2+)]`.Hence the plot E vs log `[Mg^(2+)]` is linear with positive slope intercept=`E^(@)`.
