We did a reaction in which we reacted copper sulfate with excess aluminum (all in water). Our result was a precipitate, copper metal, and aluminum sulfate which is soluble and thus aqueous within solution. So our end product is a solution with copper metal and the excess chunks of aluminum. I need another experiment or just a method at least, through which i can extract the excess aluminum. I know filtering would be required but i am unaware of how i am to approach separating solid copper and aluminum. Help or suggestions will be appreciated.
By "extract" i mean i that the solid aluminum floating in there must be taken out of solution as aluminum so it can be subsequently studied, weighed, and whatnot.
however the problem is that once i have filtered copper and aluminum metal from the solution, possibly through filtration, i have no idea how to separate the two.
Even if one suggests, to not filter and attempt something in solution, i'm clueless.
