Question:

How does a Copper (II) Chloride and Aluminum foil lab relate to the real world?

I know that the aluminum dissolves in the solution but i don't quite know how that happens in the real world and or relatesHelp? Please! and Thank you [:

Answer:

This is a redox reaction (that means REDuction and OXidation)The aluminum dissolves and elemental copper precipitates because it has higher chemical potentialBasically what's happening is electrons are being transferred from solid aluminum into the copper ion, causing it to precipitate and causing the aluminum to dissolveWhat is that like? Well, basically it's like both halves of a batteryA similar thing happens with lead-acid batter like those used to start carsWhen the battery is being used up, the electrons flow from solid lead, forming lead sulfateWhen the battery is recharged, the electrons move back into the lead ion, reforming solid leadIn this experiment, both processes are occurring simultaneouslyHope this helps.
