# Problem: Suppose that an alkaline battery was manufactured using cadmium metal rather than zinc. What effect would this have on the cell emf?

###### FREE Expert Solution

We are asked to determine the effect of changing the metal used in the alkaline battery, cadmium (Cd) metal rather than zinc (Zn)

To calculate for the standard cell potential, the following equation is used:

$\overline{){\mathbf{E}}{{\mathbf{°}}}_{{\mathbf{cell}}}{\mathbf{=}}{\mathbf{E}}{{\mathbf{°}}}_{{\mathbf{cathode}}}{\mathbf{-}}{\mathbf{E}}{{\mathbf{°}}}_{{\mathbf{anode}}}}$
