The Economic demonstrator: prepare it once, use it many times. V. liquid-liquid phase transition phenomena
Abstract A simple and economic way of conducing demonstration experiments about liquid-liquid phase transitions is presented and discussed. Pairs of liquids are sealed in a series of ampoules and each ampoule is put in a beaker filled with either ice or hot water. Depending on the nature of the components mixed, the system can become homogeneous or heterogeneous. Three kinds of systems are discussed: a system with upper critical solution temperature (UCST), with lower critical solution temperature (LCST), and a system with both upper and lower critical solution temperature.
