The emf of the cell,

\text{Ni}|\text{Ni}^{2+}(1.0\text{M})||\text{Ag}^+(1.0\text{M})|\text{Ag}

[

E^\circ

for

\text{Ni}^{2+}/\text{Ni} = -0.25

volt,

E^\circ

for

\text{Ag}^+/\text{Ag} = 0.80

volt] is given by: (A)

-0.25 + 0.80 = 0.55

volt (B)

-0.25 - (+0.80) = -1.05

volt (C)

0 + 0.80 - (-0.25) = +1.05

volt (D)

-0.80 - (-0.25) = -0.55
