Lab Report #1 Two Base Extraction

Liquid-Liquid Extraction. The extraction technique can be used to purify compounds or to separate mixtures of compounds, such as when isolating a product from a reaction mixture (known as an extractive work-up). It also has applications in the isolation of natural products, as in the extraction of caffeine from tea leaves.

Liquid liquid extraction 1

Introduction to Liquid-Liquid Extraction. Liquid-liquid extraction (also known as solvent extraction) involves the separation of the constituents (solutes) of a liquid solution by contact with another insoluble liquid. Solutes are separated based on their different solubilities in different liquids.Separation is achieved when the substances constituting the original solution is …

7.7: Liquid

Mar 25, 2020· In liquid-liquid extraction, water is almost always one of the two solvents used. Because the process requires that the two solvents do not form one substance, an immiscible second solvent is necessary. In chemistry, two substances are immiscible when they do not mix together if they make contact.
