    POST LAB QUESTIONS​

    1. Another type of reaction is redox (oxidation-reduction). Which of the three reactions (decomposition, single displacement, or double displacement) explored during this lab can also be classified as redox reactions? Explain.

     

     

     

     

     

    ​ 2. An activity series can be used to predict whether a single displacement reaction will occur as written. Any metal on the list can react when placed into solutions containing ions listed below it in the activity series. Access an activity series (from either the course textbook or by doing a Google search) and briefly explain how it summarizes the results of the reactions observed in part B.  ​

     

     

     

     

     

    ​  

    ​ 3. For part C, did any reactions not produce a precipitate? If yes, which one(s)? Would these still be classified as chemical changes? Explain.  ​
