Separation and purification Separation and purification, in chemistry, separation of a substance into its components and the removal of impurities. There are a large number of important applications in fields such as medicine and manufacturing. Since ancient times, people have used methods of separating and purifying chemical
Many liquid liquid extractions are based on acid base chemistry. The liquids involved have to be immiscible in order to form two layers upon contact. Since most of the extractions are performed using aqueous solutions (i.e., 5 % NaOH, 5 % HCl), the miscibility of the solvent with water is a crucial point as well as the compatibility of the

Extraction in chemistry is a separation process consisting in the separation of a substance from a matrix.It includes Liquid liquid extraction, and Solid phase extraction.The distribution of a solute between two phases is an equilibrium condition described by partition theory. This is based on exactly how the analyte move from the water into an organic layer.

Publisher Summary. This chapter discusses the principles of solvent extraction of organic and mineral acids. Recovery and concentration of organic acids, as well as separation of acid mixtures, have attracted great interest among researchers, especially in connection with their recovery from fermentation broths, reaction mixtures, and waste solutions.
Jul 20, 2008·Best Answer Extraction is a technique used in chemical or biochemical processes to separate two or more different compounds (solid or liquid) based on their relative solubilities in two different immiscible liquid slovents (this usually applies for liquid liquid extraction). To apply this into your example; the tea leaves contain the caffiene (alkaloid C8H10N4O2).
