When water and bromoform are mixed two layers form is the bottom layer water bromoform?

The lower layer is Bromoform, tribromomethane CHBr3 with the highest density (2.889 g/cm3), almost three times greater than of water.Trick:To simply find out if water is the lower or upper layer in a two-layer fluid system, you canadd carefully one drop of water at the top of the liquidwatch accurately the path of the falling drop and when it does 'dissolve'Then:when going down through the upper layer, then it will 'dissolve' in the lower, you may conclude the upper layer is NOT water. Orwhen 'dissolving' immediately in the upper layer then you'll conclude the upper layer is water.
