Mechanical energy is the energy of an object due to its position or motion. It is the basis of physics, as everything around us is driven by mechanical energy. From picking up objects to throwing them, mechanical energy can be seen in action every day. For example, an apple falling from a tree has mechanical energy.

For example, distillation relies on the difference in the boiling points, whereas filtration and crystallization rely on different solubilities. Now, when the two components of the mixture are enantiomers, separation becomes a lot more challenging because they have identical physical properties melting point, boiling point, and solubility .

Filtration. Filtration is a separation method used to separate out pure substances in mixtures comprised of particles—some of which are large enough in size to be captured with a porous material. Particle size can vary considerably, given the type of mixture. For instance, stream water is a mixture that contains naturally occurring biological organisms like bacteria, …

The filtration It is a process of separating a solid substance from a liquid in which it is suspended, using a mechanical means called a sieve, filter or sieve. The sieve is a porous medium that allows the passage of the smaller molecules and ductile molecules of the water, but retains the larger particles of the solid.
