Reaction with sodium bromide, chlorine water and mineral oil

Click For Summary
SUMMARY

The net ionic equation for the reaction between sodium bromide and chlorine water, in the presence of mineral oil, is represented as Br2(aq) + Cl-(aq). The discussion clarifies that chlorine water primarily contains Cl2, and the presence of Cl- is negligible for this reaction. Additionally, the reactivity of halogens is highlighted, indicating that replacing bromide with iodide would alter the reaction dynamics due to differences in halogen reactivity.

Homework Statement


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?
