Question

half cell reactions for some electrodes are given below then largest potential will be generated in which cell​

Answer 1

The correct answer is (4)$D|D^{2+}||C^+|C$

Explanation :

Since any cell is represented as ;

$M|M^{n+}|| N^{n+} |N$

And for such a cell :

$E_{cell} = E^0_{cathode} - E^0_{anode}$

Here $E^0$ is standard reduction potential .

For the cell $D|D^{2+}|| C^+|C$  :

$E_{cell }=[0.08 - (-1.12)]$ V     (  since C is cathode and D is anode )

       = 1.30 V

So, the cell$D|D^{2+}|| C^+|C$ gives the largest potential in compare to other cells .
