Given the data at $25\, ^oC$:
$Ag + I^{-} \rightarrow AgI + e^-$,$E^o = 0.152\, V$
$Ag \rightarrow Ag^{+} + e^-$,$E^o = -0.800\, V$
What is the value of $\log K_{sp}$ for $AgI$? $(2.303\, RT/F = 0.059\, V)$

Suppose that an alkaline dry cell was manufactured using cadmium metal rather than $Zn$. What effect would this have on the standard emf of the cell? The standard reduction potential $E^o_{Cd^{2+}/Cd} = -0.40 \ V$ while $E^o_{Zn^{2+}/Zn} = -0.76 \ V$.

Write the reactions for the following:
$1.$ Oxidation and reduction reactions of a lead storage cell.
$2.$ Cell reaction of a $Ni-Cd$ cell.
$3.$ Anode,cathode,and overall reaction of a mercury cell.
