Effect of Concentration and Salt Bridge Change on Ni/Sn Cell

CHEM-U5WKFK

Given the cell at $25°C$ below:

$$\textrm{Ni}|\textrm{Ni}^{2+}(2.00\textrm{ M})||\textrm{Sn}^{2+}(0.750 \textrm{ M})|\textrm{Sn}$$

After the $\textrm{Ni}^{2+}$ solution is diluted by a factor of $2$ (the volume is doubled by adding water) and the salt bridge is removed, what is the cell potential?

A

$-0.131\textrm{ V}$

B

$0.00\textrm{ V}$

C

$0.118\textrm{ V}$

D

$0.127 \textrm{ V}$

E

$0.131 \textrm{ V}$
