If you add 1 drop of 5% bromine solution in hexane to 1mL each of 5% solution of lard, olive oil, and corn oil dissolved in hexane, what happens to the bromine that causes each mixture to turn colorless?
If you continue adding drops of bromine to each, eventually the lipids change color. For our experiment it took 14 for lard, 23 for olive oil, and 35 for corn oil.
