Today’s Goal: Students will be able to determine the best metal to use for reclaiming copper from
waste solution. Focus: Which metal is best at reclaiming copper from the used copper chloride
solution?
Main Learning Goal: Identify types of hazards and the appropriate ways to handle and dispose of
them. This includes being able to compare and contrast physical and chemical methods of waste
management
Date:
Thurs 12/12/13
Title:
Activity 27, Reclaiming the Metal, Day 2
Warm Up: The formulas below represent the chemical reactions from today’s lab.
Copy each, identify and count the atoms for each of these formulas on both the
reactant side and the product side. Is the equation balanced?
3CuCl2 (aq) + 2Al (s)
3CuCl2 (aq) + 2Fe (s)
CuCl2 (aq) + Zn (s)
2AlCl3 (aq) + Cu (s)
2FeCl3 (aq) + 3Cu (s)
ZnCl2 (aq) + Cu (s)
(aq) means liquid (aqueous),
(s) means solid


I will be checking Reflection x 2, analysis 1-3 from Tuesday. I will
check study guide tomorrow.
We will:
 Review Warm up from yesterday and today.
 p. B-71 Read Introduction and Challenge
 Follow procedures 1-10 on p. B-72-73 as teacher demonstrates. Record results
in chart.
 Review Analysis Question 1, p. B-73
 Update chart “Treating Waste” with positives and negatives
 Discuss results of investigation and review chart on p. B-74
 Complete Analysis 3, p. B-74 using writing guide
BEFORE LEAVING CLASS:
Reflection: Describe what you did and/or learned today…
Homework- **Analysis Question 3- p. B-73 using writing guide
