Mixing Liquids--Mission Impossible? A Colorful Demonstration on Immiscible Systems
Eckelmann, Jens; Luning, Ulrich
Journal of Chemical Education, v90 n2 p224-227 Feb 2013
Two demonstrations are presented that show the immiscibility of five or six layers of liquids. The setup of both demonstrations is such that one homogeneous layer in a multiphasic mixture separates into two new layers upon shaking. The solvents used are methanol, toluene, petroleum ether or "n"-pentane, silicone oil, perfluoroheptanes, and water for the five-layer demonstration. Addition of mercury results in a sixth phase. (Contains 1 table and 6 figures.)
