Iodine oxidation/reduction

If they are mixed together:
I2 + Cl2 giving 2ICl

what is oxidised/reduced?

If the elements do combine, the most electronegative element will grab an electron, thus becoming the negatively charged ion. Also, keep in mind that atoms which gain an electron are reduced, and those which lose an electron are oxidized. (So if it's being reduced, than it's an oxidizer. If it's being oxidized, then is has to be a reducing agent).

Because chlorine is more electronegative than iodine, it will take on the role of the oxidizing agent and be reduced while the iodine will be oxidized.

thank`s for the very well described reply!

I doubt if the compound will be well described as "ionic",
but iodine will definately be "delta positive" and chlorine "delta negative"

If you drew an Molecular Orbital diagram, you'd get a better idea of
what MOs the electrons are going into when I and Cl bond

Tis true, but it's best to keep it simple at first and then get into the nasty gory details. :P
