Distillation: Separating a Liquid Mixture and Its Components

Topics: Distillation, Evaporation, Water / Pages: 5 (1044 words) / Published: Feb 4th, 2014


Distillation, one of the most significant method for separating a liquid mixture and its components, is a process that relies on differences by the ease of vaporization of the components. The purpose of this process is either the separation of a mixture of volatile components from nonvolatile materials is carried out by a simple distillation in which the material is placed to distill and heated, the vapor from the substance is removed and condensed. In this activity, we tend to separate ethanol with water. Simple distillation is employed in this process.
