Thus, aluminum has the ability to push the copper out of the copper solution (II) chloride.<\/p>\n<p dir=\"ltr\">Reaction equation:<\/p>\n<p dir=\"ltr\" style=\"text-align: center\">2Al (white solid) + 3cucl2 (blue dd) \u2192 2AlCl3 (colorless dd) + 3cu (red snake)<\/p>\n<p dir=\"ltr\">In addition to CuCl2, aluminum metals also have the ability to react with many salt solutions of weaker chemical active metals, creating aluminum salts and a new metal.
