Step-by-step explanation:
The results shows the reactivity of the halogens and how they displace one another from any solution of their compounds.
The oxidizing power of the halogens decreases from top to down on the group. This explains why the more powerful oxidizing halogens displaces the less powerful one from simple salts.
We see that chlorine is able to displace Bromine and iodine
Bromine is only able to displace Iodine
Iodine cannot displace bromine or chlorine
