<u>Answer:</u> The potential of electrode is -0.79 V
<u>Explanation:</u>
When zinc is dipped in zinc sulfate solution, the electrode formed is
Reduction reaction follows:
To calculate the potential of electrode, we use the equation given by Nernst equation:
where,
= electrode potential of the cell = ?V
= standard electrode potential of the cell = -0.76 V
n = number of electrons exchanged = 2
(concentration of pure solids are taken as 1)
Putting values in above equation, we get:
Hence, the potential of electrode is -0.79 V
