3 ·         Provide at least 1 example of a reversible process (either physical or chemical).  What has to be done to the process to make it reverse? 



Part 2—Copper (II) Chloride System - 

Cu(H2O)62+(aq) + 4Cl(aq) + heat     CuCl42–(aq) + 6H2O(l)

Blue                                                             Green

 

Test

Tube

Procedure

(Impacts)

Predictions

Observations

(Result/Shift)

1

No tests (control)

   

2

Add 4M NaCl dropwise until change is observed

*increases concentration of Cl─ in the system

   

3

Add 0.05M AgNO3 drop-wise until change is observed

*decreases concentration of Cl─ in the system

   

4

Add H2O dropwise until change is observed

*increases concentration of H2O in the system

   

5

Add acetone dropwise until change is observed

*decreases concentration of H2O in the system

   

6

Place in hot water bath for 1-2 minutes

*adds heat to the reaction system

   

7

Place in ice water bath for 1-2 minutes

*removes heat from the reaction system

   

 

Reflection

Revisit the pre-lesson questions for this activity and your answers.  Based on what you learned in this activity:

 

  •         In this lesson, we looked at several examples of systems and surroundings.  Describe the system and surroundings from part 2. ( discusses systems and surroundings)

 surroundings – everything outside of the system being studied      system – the reactants and products in a chemical reaction

  •         In this lesson, you impacted several chemical systems in various ways.  Describe all of the impacts tested in part 2.

 

  •         Based on this lesson, how would you define a reversible reaction?  How would you define equilibrium?
