Lab: Observations of an equilibrium reaction
Objective: You will make observations of an equilibrium system and from these observations you will utilize Le Châtelier’s Principle to determine the correct equilibrium equation. The following are the components of the equilibrium system you will study:
Students do the lab and do the following write-up:
Observations, questions, and Conclusion:
1. Neatly describe all your observations.
2. Write the correct equilibrium reaction using the components listed above.
3. Justify your equilibrium reaction with your observations.
4. What would happen (if anything) to the system if lead (II) nitrate was added? Explain.
5. What would happen (if anything) to the system if air pressure was significantly increased? Explain.
6. Would the result have been any different if potassium chloride was added instead of sodium chloride? Explain. Could the fact that the dissolving of potassium chloride is an endothermic reaction change your answer? Explain.
7. Summarize Le Chatelier’s principle in your own words.
