Laboratory Date Name TA Experiment 2- Post- lab Questions I. Chloroform and cyclohexane are organic liquids that are insoluble in water (see Table 2.2), and this causes two distinct liquid phases, an organic phase and a water phase, to form when these organic liquids are mixed with water. However, in a chloroform/water mixture, the water phase is on the top and the organic chloroform phase is on the top, whereas in a cyclohexane/water mixture, the water phase is on the...
