Question: Can we construct an electrochemical cell with two half-cells composed of znso4 solution and zinc electrodes? explain your answer.

Yes, we can construct an electrochemical cell with two half-cells composed of ZnSO4 solution and zinc electrodes, but only if the concentration of ZnSO4 in the two half-cells is different. This will create a difference in the electrode potential of the zinc electrodes, which will drive the flow of electrons from the anode (the electrode with higher concentration of ZnSO4) to the cathode (the electrode with lower concentration of ZnSO4). The salt bridge will maintain the electrical neutrality of the solutions by allowing the migration of ions. ¹⁵

The diagram below shows an example of such an electrochemical cell:


The cell reaction is:

Zn(s) + Zn2+(aq) → Zn2+(aq) + Zn(s)

The cell potential is given by the Nernst equation:

$$E_{cell} = E^0_{cell} - \frac{RT}{nF} \ln Q$$

where $E^0_{cell}$ is the standard cell potential, $R$ is the gas constant, $T$ is the temperature, $n$ is the number of electrons transferred, $F$ is the Faraday constant, and $Q$ is the reaction quotient.
