Lab 3-1 B: The Synthesis and Detection of Copper Allen Chen Grade 9
2012/12/4
Purpose: The purpose of this experience is to complete the single replacement reaction. I am hoping to achieve the reaction of isolating copper from Copper (II) Chloride{ 3Cu(II)Cl2 + 2Al = 3Cu(II) + 2AlCl3} , and letting Cu react with O throughout the process of inflammation{ 2Cu(II) + O2 = 2CuO}.
Hypothesis:
According to the characteristic of other types of single replacement reaction, if Copper(II) Chloride add with aluminum, we pretend that it will separate the copper. The result will form copper and aluminum chloride.
Independent variable: Copper (II) Chloride and Aluminum
Dependent variable: how many aluminum to make reaction
Controlled varibales: amount of Copper (II) Chloride that make reaction
Materials / Apparatus:
Copper (II) Chloride solution
Two 400ml beakers
Aluminum foil
Crucible tongs
waste container
dilute hydrochloric acid solution (HCI)
wooden splint
paper towel
Bunsen burner
Procedure: Refer to p. 81 of BC Science 9
Data / Observations / Results:
Title: Add aluminum to Copper (II) Chloride and separate Copper from copper Chloride
