Construct the following diagrams and label them.An electrochemical cell with a salt bridge using copper and zinc electrode and sulphate salt solution (galvanic cell)
To construct the diagram of an electrochemical cell with a salt bridge using copper and zinc electrodes and a sulfate salt solution, follow these steps:
1. Draw a rectangular container representing the cell.
2. Label one side of the container as the zinc electrode (Zn) and the other side as the copper electrode (Cu).
3. Connect the two electrodes with a salt bridge, represented by a line connecting the two sides of the container.
4. Fill one side of the container with zinc sulfate solution (ZnSO4) and the other side with copper sulfate solution (CuSO4).
5. Label the zinc electrode as anodic and the copper electrode as cathodic.
6. Show the flow of electrons from the zinc electrode to the copper electrode by drawing an arrow from Zn to Cu.
7. Label the half-cell reactions on each electrode:
- At the zinc electrode: Zn(s) -> Zn^2+ + 2e^-
- At the copper electrode: Cu^2+ + 2e^- -> Cu(s)
After following these steps, you will have constructed a diagram of an electrochemical cell with a salt bridge using copper and zinc electrodes and a sulfate salt solution.
