Abstract: Experiment 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

Study of Water Purification Methods Water is the most essential component of life on Earth. In the United States‚ the average person uses about 75 gallons per day of freshwater. Most of this water is pre-treated in facilities and comes out of the tap clean and ready for drinking‚ a fact many take for granted. If you are camping and hiking you won’t always have access to this source of healthy‚ potable water. Unfortunately‚ many water sources in the wilderness include microorganisms‚ bacteria

Nitration and Purification of Bromobenzene Abstract: An electrophilic aromatic substitution reaction was performed on bromobenzene with nitric acid producing both 2-bromonitrobenzene and 4-bromonitrobenzene. Products of the reaction were purified through multiple recrystallizations and column chromatography creating multiple crops of a yellow powder. The percent yield of products was determined to be 51%. The melting point of Crop 1 was found to be 110-115 °C‚ and Crop 2 was found to be 37-90

Deloris Buliner RESL201 Christopher Myers October 20‚ 2014 Purification of Judaism and Hinduism Judaism and Hinduism have different cultures and originate from different ends of the spectrum of religious development. The origin of Judaism is characterized by a dramatic break with the near Eastern religious tradition comprising of the unity of God‚ man‚ and the cosmos while Hinduism on the other hand‚ characterized by “pantheism” as the main motif in its religious outlook (Ridgeon‚ Lloyd).

Objective: Separate and purify acetanilide from a mixture by recrystallization. Compare the melting points of crude and recrystallized acetanilide. Introduction : The most common method of purifying solid organic compounds is by recrystallization. In this technique‚ an impure solid compound is dissolved in a solvent and then allowed to slowly crystallize out as the solution cools. As the compound crystallizes from the solution‚ the molecules of the other compounds dissolved
