Explanation:
I did this in class and it was a review. :)
Answer: 0.18 V
Explanation:-
![Cd/Cd^{2+}(0.10M)//Ni^{2+}(0.50M)?Ni](https://tex.z-dn.net/?f=Cd%2FCd%5E%7B2%2B%7D%280.10M%29%2F%2FNi%5E%7B2%2B%7D%280.50M%29%3FNi)
Here Cd undergoes oxidation by loss of electrons, thus act as anode. nickel undergoes reduction by gain of electrons and thus act as cathode.
=-0.40V[/tex]
=-0.24V[/tex]
![Cd+Ni^{2+}\rightarrow Cd^{2+}+Ni](https://tex.z-dn.net/?f=Cd%2BNi%5E%7B2%2B%7D%5Crightarrow%20Cd%5E%7B2%2B%7D%2BNi)
Here Cd undergoes oxidation by loss of electrons, thus act as anode. nickel undergoes reduction by gain of electrons and thus act as cathode.
![E^0=E^0_{cathode}- E^0_{anode}](https://tex.z-dn.net/?f=E%5E0%3DE%5E0_%7Bcathode%7D-%20E%5E0_%7Banode%7D)
Where both
are standard reduction potentials.
![E^0=E^0_{[Ni^{2+}/Ni]}- E^0_{[Cd^{2+}/Cd]}](https://tex.z-dn.net/?f=E%5E0%3DE%5E0_%7B%5BNi%5E%7B2%2B%7D%2FNi%5D%7D-%20E%5E0_%7B%5BCd%5E%7B2%2B%7D%2FCd%5D%7D)
![E^0=-0.24-(-0.40)=0.16V](https://tex.z-dn.net/?f=E%5E0%3D-0.24-%28-0.40%29%3D0.16V)
Using Nernst equation :
![E_{cell}=E^o_{cell}-\frac{0.0592}{n}\log \frac{[Cd^{2+}]}{[Ni^{2+]}](https://tex.z-dn.net/?f=E_%7Bcell%7D%3DE%5Eo_%7Bcell%7D-%5Cfrac%7B0.0592%7D%7Bn%7D%5Clog%20%5Cfrac%7B%5BCd%5E%7B2%2B%7D%5D%7D%7B%5BNi%5E%7B2%2B%5D%7D)
where,
n = number of electrons in oxidation-reduction reaction = 2
= standard electrode potential = 0.16 V
![E_{cell}=0.16-\frac{0.0592}{2}\log \frac{[0.10]}{[0.5]}](https://tex.z-dn.net/?f=E_%7Bcell%7D%3D0.16-%5Cfrac%7B0.0592%7D%7B2%7D%5Clog%20%5Cfrac%7B%5B0.10%5D%7D%7B%5B0.5%5D%7D)
![E_{cell}=0.18V](https://tex.z-dn.net/?f=E_%7Bcell%7D%3D0.18V)
Thus the potential of the following electrochemical cell is 0.18 V.
