Students started out with 150 mL of water in a beaker and then added 1/2 teaspoon of Copper Chloride. Then added a 15x1.5 cm piece of Aluminum foil to the solution. Then after stirring, filtered the liquid and put the sediment that was left over in a test tube. Then, Nitric Acid was added to the test tube and results were recorded.
Starting Temperature of Water: 22 degrees Celsius
Observations of Copper Chloride:
-Looks like blue sand
When Added to Water:
-Turned green when added to water
When Stirred:
-Water turned opaque and blue
-Copper Chloride dissolved
-22 degrees Celsius after stirring
After Aluminum Foil Was Added:
-Foil started to turn dark
-Liquid starting to oxidize the aluminum foil
-Foil started to fall apart
After Stirring Again:
-Foil fell apart
-Turned a rusty color
-Water turned a dark blue/gray color
