Question

DATE: NAME: Labels for Venn Diagram Comparing Electrochemical Cells AKA Galvanic cells 1. Oxidation occurs at the anode 2. оссurs 3. Reduction occurs at the cathode 4. Produces electrical energy from chemical energy 5. Separation of electrodes to create an electrical potential 6. Ions move through solution/salt bridge in response to electron movement through wire 7. Ecell<0 8. Requires an electric power source to produce chemical energy 9. Nis) Ni(NOs) (aq)||AgNO (aq)| Ag(s) 10. AG 0 11. Is a spontaneous chemical reaction 12. Used for metal plating 13. Used to power small electronic devices process 14. Comprised of two half-cells each of which is a balanced chemical 15. Ecell> 0 16. AG> 0 17. Corrosion is an example of it 18. Ni(s) Ni(NO ) (ag)||Mg(NOs)2(ag)| Mg(s) 19. Is an electrical circuit 20. Used to produce Al metal from its ore

Answer 1

VOLTAIC ELECTROLYTIC 1,4,5, 7, 8, 12, 10 6,0,9 / 3 318,20 11, 13, 15, 16, 17,

Reason for choice of labels:

1. Voltaic cell is Galvanic cell.

2,3 : it is common to both cells.

4 : chemical reaction produces electrical energy

5 : Electrodes are in separate containers in Voltaic cell

6. Salt bridge is only in Voltaic cell

7. Electrolytic cell only has non spontaneous Redox reaction, so, E cell is negative.

8. Electrolytic cell uses electrical energy to drive non spontaneous reaction.

9. It is a spontaneous reaction.

10. This occurs in electrolytic cell because electricity drives reaction.

11. It is characteristic of Voltaic cell.

12. Electroplating uses electrolytic cell.

13. For example, Dry cell is. a Voltaic cell.

14. Both are composed of half cells.

15. Voltaic cell has positive E cell

16. Voltaic cell has spontaneous reaction.

17. Corrosion is spontaneous.

18. It is a non spontaneous redox reaction.

19. Both constitute electrical circuit.

20. Al ore is reduced electrolytically to form Al metal.
