    Chromatography: Please help!!

    What is the visualizing reagent used for Cu(II), Cd (II), Ni(II) and Co(II) ions when performing paper chromatography?
    Are there any special visualizing reagents for transition metals?

    put the paper in a NH3 chamber, some of the transition metals will show up as very brilliant colors,

    there are others (can't think of them right now) but NH3 is a good general one
