Calcium chloride has polar properties where as anhydrous aluminum chloride has stronger non-polar properties as it is covalently bonded between the atoms of aluminium and chlorine.Calcium chloride being insoluble in non-polar solvents, such as acetone,add acetone to the mixture in a flask and leave it for about 10 minutes.Anhydrous aluminum chloride dissolves,leaving Calcium chloride undissolved.Filter the mixture to
obtain aluminum chloride as a filtrate and Calcium chloride as a residue.Dry the residue between filter papers.
