Solutions of transition metals. From left to right are: Cobalt (II) chloride (CoCl2). Iron (II) chloride (FeCl2). Iron (III) chloride (FeCl3). Copper (II) chloride (CuCl2). When sodium hydroxide is added to these solutions a distinctive coloured precipitate of insoluble salt is formed which helps to identify them. This can be used in forensics as well as chemistry | |
