Using your understanding of these lab and your lab notebook, answer the following questions in the space provided.
1. In this lab, when you created the Copper (II) chloride solution, did a chemical reaction occurred? Circle Yes or No.
2. Write down the temperature you observed during the reaction in this lab. __________________°C
3. Was the Aluminum chloride solution part of filtrant or filtrate? ________________
4. What was the red/brown colored precipitate that you observed in this chemical reaction. ________________
5. Was it ok that you simply used the scale on side of beaker to measure what volume of water you need to add to teh solid Copper (II) chloride dihyrate. Why?
6. In the Observation of a Chemical Reaction lab, which observation of a chemical reaction that you observed actually was not caused by the chemical reaction? ____________(Do not have to explain why).
4. In the Endoexothermic reaction lab, did all the reactants react in the lab or was there some unreacted reactant left after the chemical reaction stopped? How do you know or how do you don't know? Explain.
5. For the Observation of a Chemical reaction lab, If you still had a blue color to the filtrate (the solution that goes through the filter paper), what does it mean and how can you fix it?
6. In the Observation of a Chemical reaction lab, what happened to the material/substance/particle that caused the solution to be be blue (i.e. what did it become)?
