Question about kationts

  1. Feb 1, 2007 #1
    Hi all,

    I have a small question. I have checked it: http://neon.chem.ox.ac.uk/vrchemistry/LiveChem/transitionmetals_content.html [Broken]

    and I am very confusing. There is some kationts of metal and these are liquid !
    For example mangan kationt : Mn+7 is red liquid. Is it possible ?

    PS:I am sorry for my englisch, its not good !

    I think you are referring to cations. The ions you are looking at are actually compounds that are dissolved in water. The Mn + 7 comes from a salt (i.e. Mn(2)O(7)) being dissolved in water. The Mn+7 is what give it the charactersitic red color, but there is a counterion also in the liquid. It is not possible to have a liquid of only Mn+7 as the charge of each ion would repel each other ion.

    Thank you for your answer.
    I was only confused about label Mn+7.
