Question
LEARNING CHECK 4.3
Competencies: 12. describe the electrochemistry involved in some
common batteries: a. leclanche dry cell b.
button batteries c. fuel cells d. lead storage
battery
13. apply electrochemical principles to explain
corrosion
1. Write the cell reactions which occur in lead storage battery
a. when the battery is in use
b. when the battery is on charging
2. Write down the reactions taking place at the electrodes of a mercury cell. At
anode:
The oxidation of zinc metal takes place and the zinc ions react with the OH-
ions from the electrolyte to form zinc hydroxide.
3. Discuss the advantages of a fuel cell over mercury cell'
4. How can metals undergo corrosion?
5. Discuss some ways to prevent corrosion
