Question: Consider the cell $Cd\,(s)|C{{d}^{2+}}(1.0M)||C{{u}^{2+}}(1.0M)|Cu\,(s)$ If we wish to make a cell with a more positive voltage using the same substances, we should

1) Increase $[C{{d}^{2+}}]$ as well as $[C{{u}^{2+}}]$ to 2.0 M

2) Reduce only $[C{{d}^{2+}}]$ to 0.1 M

3) Increase only $[C{{u}^{2+}}]$ to 2.0 M

4) Decrease $[C{{d}^{2+}}]$ as well as $[C{{u}^{2+}}]$ to 0.1 M
