I had a lab yesterday that involved dumping some copper chloride in water, observing the temp before stirring and stir. then it says add a piece of aluminum that was in a loose ball shape WITHOUT STIRRING. can someone please explain what happens when these things are done? i had lab partners that just dumped everything together and stirred everything the whole time, they finished the lab in about 5 mins with the thermometer out of the beaker half of the time so i don't know what went on and neither did they (not surprisingly)

My guess is that aluminum is a reactive enough metal that it would ionize in water and reduce the copper to the elemental state. So I guess you would see a copper precipitate after a while.
