Experiments in Dyes and Dyeing Means to better understand the nature of intermolecular forces

Abstract

The nature of intermolecular forces is responsible for a vast number of phenomena in our everyday life. It can explain for example, trends in solubility, differences in boiling points, adsorption effects (chromatography) and many other observations. Our teaching experience shows that it is not easy to explain this issue to students of all levels, but better understanding can be achieved through experimentation. One of the most effective practical experiences we offer our students at BIU or in high schools deals with dyeing fibers with synthetic or natural dyes.
