    So, in a separating funnel, there is Iodine dissolved inCyclohexane, and there is also an aqueous solution. I believe the cyclohexane solutionwill be on top as it is less dense (i think).
    I was wondering, if we add CCL4 (Methane tetrachloride) to the separating funnel – which solution would change colour first?

    You wouldn't add CCl4, it is extremely toxic to the liver.

    Carbon tetrachloride is much more dense than water so would form a third layer at the bottom. It would not be in contact with the cyclohexane layer.
