quote:Originally posted by Mr AndrewI think it might be possible to precipitate aluminum in a powder form in a double replacement reaction. Pour sulphuric or hydrochloric acid on your aluminum chunk and collect the aluminum salt produced (you can also light the hydrogen gas on fire and make a large fireball if you want--loads of fun!!). Next take the aqueous aluminum salt and add a more reactive metal than aluminum (try magnesium, it's not hard to come by). The aluminum metal should precipitate and another metal salt will be be formed (aqueous of course). Filter out the aluminum metal (which should be in the form of a powder[?]) and dry. Do not heat the powder to aid in evaporation as the powder will ignite!!! That is a bad idea.
