Homework 3
1. HOMEWORK: Methods of Separating Mixtures First: Read Chapter 3 sections 3 and 4 (Mixtures of Matter and Elements and Compounds). Second: Read this file. Third: Exemplify the use of methods of separating mixtures in: recycling processes, purification of water, air and solids. Before writing your examples, do research and cite your sources. DUE DATE: Wednesday 24th, 2011
3. Methods of separating mixtures Filtration Decantation Distillation Paper chromatography Centrifugation Magnetization
4. Separates a solid from a fluid (liquid or gas) Uses a porous barrier: filter paper Use gravity or gravity enhanced by a vacuum. Filtration
5. Used to separate immiscible liquids Done by carefully pouring one of the solutions into another container Used to separate insoluble solids Decantation
6. Mostly used for homogeneous mixtures Separates substances by their boiling points Condense the gas into a liquid and collect Distillation
7. Composed of a mobile phase and a stationary phase Mobile phase: usually a gas or a liquid that travels through the stationary phase Stationary phase: chromatography paper Paper Chromatography
8. Uses the centrifugal force in order to sediment compounds in a mixture. Centrifugation
Notes de l'éditeur
Liquid passes through leaving the solid behindRemove air pollutionWaste treatment
liquid zinc and liquid silver are immiscible in liquid
DISTILLED WATERDISTILLED BEVERAGES: higher alcohol concentration low boiling point
Travel at different speedsFor testing purity of compoundsIt has the ability to separate, identify, and quantitate the compounds that are present in any sample that can be dissolved in a liquid
