The separated substances form bands of colour called chromatograms. Sedimentation is a process by which heavier impurities present in liquid normally water settle down at the bottom of the container containing the mixture. What is the formula for calculating solute potential? No chemical changes need be involved, so the substances will retain their chemical identity throughout the separation process. Oil and water.

Chemical separation methods, such as extraction and chromatography, are based on chemical interactions between the mixture's components, or, to be more precise - the differences in the strengths of the interactions of the different materials in the mixture with another material which is not a part of it. The concept of separation of mixtures is also introduced since nearly every element or compound is found naturally in an impure state such as a mixture of two or more substances, and it is common that chemical engineers use separation techniques to separate mixtures into their individual components. Filtration. 4 How can we apply decantation method in our everyday living? They are the air we breathe, the food and drink we consume and the fabrics we wear.
