Coloured salts

  1. Jan 29, 2012 #1
    why some salts are coloured although all the electrons are paired in it?
    Ex: potassium dichromate, potassium permanganate, silver bromide/iodide.

    You don't need unpaired electrons to have a colored salt.

    Its because of "charge transfer" that some salts inspite of having paired electrons have bright intense colour like KMnO4

    can you please explain this charge transfer effect, and in which type of this will be observed?
