Question

Ii. Using the equation Erd-Ecathode - Eanode, calculate the overall cell potential for the cell in step b.

Be sure to show all steps completed to arrive at the answer

Answer 1

0.637 V

Step-by-step explanation:

The balanced redox reaction is:

Here Zn undergoes oxidation by loss of electrons, thus act as anode. Lead undergoes reduction by gain of electrons and thus act as cathode.

Where both are standard reduction potentials.

= -0.763

= -0.126

The standard emf of a cell is 0.637 V
