Summer 2012 Separatory Funnel Separation of immiscible liquids Extraction To pull out a compound from one layer into another A compound partitions more toward where it is more soluble equilibrium. A Physical Property. A . Definition of solubility:. . A measure of how much solute can dissolve in a solvent at a given temperature. .. What is a . solvent. ?. A substance that dissolves another substance.. S343. 1. Separatory. Funnel. Separation of immiscible liquids. 2. Extraction. To . pull out. a compound from one layer into another. A compound partitions more toward where it is more soluble (equilibrium). Recall, solubility is the amount of solute that dissolves in a given volume of solvent at a certain temperature. .. Solubility is determined by the intermolecular attractions between solvent and solute particles. Chapter 18. Is . AgCl. soluble or insoluble?. Dissolution Reactions and . K. sp. Expressions. AgCl.
