how do you recover aluminum chloride from a solution of copper (ii) chloride and water and aluminum?When a copper chloride solution is exposed to aluminum, the aluminum dissolves because the aluminum reacts with the copper chloride solution and an electron exchange takes placeAluminum gives electrons to the copper ionsThis causes the copper ions to turn into copper metalAt the same time aluminum metal turns into aluminum ions Al metal + Cu+2 ions - Al +3 ions + Cu metal The solution ions become a metal (Cu) which are the orange red particles you see at the bottom of the solutionThe new aluminum ions have different properties than the aluminum metal To get the reaction that you want, AlCl3, you need to super saturate the aluminum in solution - so first you need to remove all of the copperAnd note that your precipitate will contain the solid copper too.Other related question
