COURSE INSTRUCTOR DR. NANCY MARASHI. |

Background:
During this experiment students will take a mixture and separate it into its’ pure substances. A mixture is a combination of two or more substance. These substances cannot be combined chemically but more physically. The pure substances are substances that cannot be separated any more by physical means. The students will learn the difference of these two meanings during the experiment.
The pure substance will be separated by something called their physical means. The physical means are the boiling point and solubility that each substance contains. …show more content…
Pour the sand out, when dry, into the weigh dish to find the net mass on the scale.
For the next substance the students will weigh a separate paper cup and record the data. The students will fold a filter paper into a funnel shape and weigh it. Place the folded filter paper into the plastic funnel and begin to pour the benzoic crystals and salt mixture through the filter into the second weighed paper cup. After the cup has drained into the second paper cup the student will pour 5ml of chilled distilled water through the funnel to get all of the salt out. The student will wrap the filter paper full of benzoic crystals in paper towels and place it somewhere safe until it is completely dry. After the substance is dry the student will get the net mass of the benzoic crystals be weighing the folded filter paper and subtract its original weight.
The final substance to be measure is the salt. Place the paper cup full of water and sodium chloride aside until all of the water has evaporated. Weigh the paper cup with the salt crystals and subtract the cups’ original weight to get the net mass of the salt crystals. Record the data in the data table.
To finish the table the students will add all of the mass together and find the percent of each substance in the mixture. The percent will be taken by dividing the weighed grams by the total weight and then multiply by one hundred.
Lastly, the students will clean up, wipe down surfaces and clean all of the equipment.

Mass and Crucible Essay

REPORT Separation of a Mixture PURPOSE: To separate a mixture based on the properties of its substances. Mixtures that are not chemically combined can be separated based on their unique physical properties. The use of phase changes support the separation of distinct substances in a heterogeneous mixture. Simple techniques such as sublimation, decanting, evaporation and extraction can be used for the different types of phase changes. THEORECTICAL: The procedure of separating a mixture of three…

A Separation and Purification Scheme Essay

55 consists of devising a separation and purification scheme for a three component mixture. The overall objective is to isolate in pure form two of the three compounds. This was done using extraction, solubility, crystallization and vacuum filtration. The experiment was carried out two times, both of which were successful. Background Information: This experiment combined all the knowledge of the previous labs performed throughout the semester. An unknown mixture containing an organic acid…

methods of procedure that can be used for later experiments. This experiment involves the separation of benzoic acid from a more crude form, consisting of benzoic acid, methyl orange, a common acid/base indicator, and cellulose, a natural polymer of glucose (Huston, and Liu 17-24). The technique that is used to perform this separation is called extraction. Extraction is a systematic process of separating mixtures of compounds, taking advantage of the affinity differences of compounds to separate them…
