    Acid Etching

    Ferric chloride is. Because the Fe is essentially stripped of its electrons by the Cl atoms attatched to it, the Fe becomes pretty strongly positive. So while Fe(III)Cl has no protons to donate, it can strip electrons off molecules and act as a lewis acid.I know you can get it on eBay and Amazon. As for brick-and-mortar shops...maybe try Fry's electronics or a science surplus store? I've never seen it on a shelf.
