I'm doing a science experiment:What happens when copper chloride when it was added to water? Is it a chemical change?What physical change occured??When doing this experiment, I think a new substance was formed when aluminum was added to the liquid. It looks like copper. Is it possible it is? Where did it come from though?Thanks!!
Because Copper chloride is an ionic compound, it will dissociate in water, meaning that it will split into ions. I'm not sure whether it is chemical or physical. It is most likely physical, but the ionic structure will reform when the solvent is dried. When aluminium is added, most likely, a single replacement reaction had occurred. This means that the aluminum switched places with the copper, and formed a solution of aluminium chloride. The copper will precipitate out. This is a chemical change due to the presence of a chemical reaction.
