Lab 3: separation of mixtures june 12, 2014 admin leave a comment in this lab we are going to investigate different ways to separate mixtures of substances by taking advantage of their physical properties it will be inquiry-based, and you and your group will get to decide which techniques you want to use to separate a heterogeneous mixture. Paper chromatography is the use of a special kind of paper used to separate different chemicals from a mixture here is how it works separation of mixtures by paper chromatography this method is often used in the food industry it is used to identify chemicals (coloring agents.
Separation of mixtures - separation of mixtures substances are mixed physically in a mixture element is a pure substance made up of only one kind of atoms eg sodium, hydrogen, carbon. Mixtures are all able to be separated by exploiting some physical property no chemical changes need be involved, so the substances will retain their chemical identity throughout the separation process. The purpose of the experiment was to separate an initial heterogeneous mixture composed of 500 grams of salt, 200 grams of sand, 500 ml of water, 1500 grams of pebbles, and 100 gram of iron filings, and leave as much salt as possible remaining.
