Density and Miscibility

The liquids did not mix — so what do density columns have to do with it? The seventh part in a series of nine provides the theoretical explanation of why density columns do not mix. The lesson covers the topics related to mixing and hydrogen bonds. These topics allow the class to gain an understanding of the chemical properties of water and its interactions with other substances.
