11.16. Aluminium trifluoride is insoluble in anhydrous but dissolves on addition of . Aluminium trifluoride precipitates out of the resulting solution when gaseous is bubbled through. Give reasons.
is a covalent compound and has a very strong intermolecular hydrogen bonding. So, it does not provide any ions, as a result, does not dissolve int it. is an ionic compound and it can give ions. Thus can dissolve in it and form
When is added to the solution, it can replace aluminium and formed a complex of itself and can precipitate out.
