Investigating the reactions of halogens and their compounds A) When bromine solution is added to cyclohexane, two layers are formed. The top layer is orange and the bottom layer is yellow. Non soluble solvent cyclohexane layer is at the top. Two layers of solution are formed because cyclohexane is non-polar and bromine is polar so they don't mix, this is immiscible. Cyclohexane is less dense than water so it is at the top. Bromine added to cyclohexane solution turns orange because the aqueous layer of bromine moves to the cyclohexane layer. B) When halogen solution is added to solutions of potassium halides followed by the addition of cyclohexane to the mixture two layers of solution is always formed. For example when chlorine solution is added to potassium bromide solution followed by cyclohexane, the upper layer is light brown/ orange and the bottom layer is light yellow. The top layer becomes orange because...
