extraction‚ also known as liquid extraction and partitioning‚ is a method to separate compounds based on their relative solubility in two different immiscible liquid‚ usually water and organic solvent. It is an extraction from one liquid phase to another liquid phrase. Liquid extraction is a basic technique in chemical laboratories‚ where it is performed using a separator funnel. This type of process is commonly performed after a chemical reaction as part of the work-up. Liquid–liquid extraction is possible

of seperation in which a solid or solution is contacted with a liquid solvent (the two being mutually insoluble) to transfer one or more components into to the solvent. There are two main types of extraction in chemistry‚ namely: Liquid-liquid extraction or solvent extraction‚ which is divided into two types. (simple and multiple) and solid-liquid extraction. The type of extraction that was used in this experiment was the solid-liquid extraction. To extract the caffeine from the dried tea leaves‚
