Chemistry / What is the reaction between hydrochloric acid and aluminium?

« on: 13/10/2008 02:54:26 »

I was doing the old "hydrochloric acid with the can in it" trick,and i am pretty sure that it produces aluminum chloride.
what i was wondering was how to get the alcl ( aluminum chloride )out of the solution as a solid? you see when the reaction takes place the alcl is in a liquid form and i am wondering how to get it into its solid form and extract it from the solution?

please help, thanks allot

« on: 09/10/2008 03:32:46 »

i have read that when you dream that the brain is expanding its ability to learn and understand concepts and data.
