What Would Chlorine React With?

[Arjy]

If I had a box that had inside it a UV light an equal quantity of ozone (O3), and H3O+, which would be broken down because of the UV light to O, and O2, as well as H2O, and H+ because that is what the H3O+ would be broken down into. If I introduced one hypochlorite Ion (ClO−) or a chloride Ion (Cl−), what would the chloride Ion or hypochlorite Ion react with? Would it react with the H+, or the O & O2?
