Reaction with sodium bromide, chlorine water and mineral oil

  1. Oct 19, 2014 #1
    1. The problem statement, all variables and given/known data
    Net ionic equation for sodium bromide and chlorine water with mineral oil
    2. None
    3. The attempt at a solution

    Br-aq + Cl-aq → Br-aq + Cl-aq

    or
    Br-aq + Cl2aq → Br2aq + Cl-aq

    Not sure if a halogen in water is an ion or not and can't seem to find good information online about it
    Also would like to know how this would work if bromide was replaced with iodide if there is any difference.

    Chlorine water contains mostly Cl2, presence of Cl- doesn't matter.

    Your first equation doesn't describe a reaction - you start with identical mixture you end with.

    So we are left with the second equation - and it is correct.

    Do you know what is reactivity of halogens? How does it change?
