Virtual Lab: Liquid-Liquid Extraction

Separation and Identification of a Binary Mixture: Ionizable Base and Non-ionizable Compound

Liquid-liquid extraction is a very common technique used in multiple fields from quality analysis of pharmaceutical products to refining chemicals on an industrial scale. This method uses the varying acid-base and solubility properties of organic molecules to separate them. In this virtual lab, you will perform the separation of an unknown solid mixture composed of an ionizable base and a non-ionizable (neutral) compound. The simulation will randomly assign you an unknown mixture to work with.

As you work through this simulation, you will:

Before You Begin

Review the Liquid-Liquid Extraction Laboratory Unit so you feel confident with concepts of acid-base chemistry, laboratory equipment, and techniques. This virtual lab is for you to make intentional decisions and not ‘guess’ what the right answer would be! If you struggle with decisions when completing the lab, review relevant sections of this laboratory unit again or reach out for help.
