Hi
If a piece of aluminium foil would fall during evaporation (severall days) in HCL solution (pyrex) it would dissolve.What would someone after evaporating the whole liquid do for cleaning the remaining HCL crystals from alu residue…?
First thing that comes to my mind is mixing with solvent and start over (not shure 100% effective)

that's right.
basify, pull with nonpolar.

don't use aluminum when acidifying/basifying.

Aluminium and hydrochloride result in aluminium chloride and hydrogen.

Aluminium chloride is soluble in several non-polar solvents which means that you could pull it again when basifying/salting depending on the solvent used. Or am I missing out on something and does the basifying process somehow neutralizes the aluminum chloride?

At room temperatures the solubility is not that high but in some solvents quickly rising at higher temps.

In this link the solubility of aluminium chloride in several non-polar solvents.

solubility of aluminium chloride

inorgaic salts are generally more soluble in polar solvents
than nonpolar solvents

and it will no longer be aluminum chloride once you basify.
you'll have several ionic species in solution, and of course, charged
particles do not migrate into nonpolar solvents.

Exactly, as benzyme said.

@poekius, there is not such a thing as aluminium chloride when aluminium chloride is dissolved in water. It becomes a bunch of charged aluminium and chloride ions floating happily in water dissociated. Same goes for practically all the salts.

Of course, there is the aluminium chloride powder/crystals in solid form which might(?), as per the links you provided be soluble in non-polar solvents.

Ok thanks guys for explaining. I started learning a little bit about chemistry by this forum and my chemistry skills are very basic (only 3 years in high school 20 or so years back). I shouldn't have replied in this thread in the first place especially because the answer was given by benzyme

thank you all
