various techniques can be used such as sublimation, evaporation, extraction, filtration, decantation, and more. In this lab, benzoic acid, benzocaine, and 9-fulorenone were mixed and acid-base extraction, separatory funnel extraction, drying organic solutions, suction filtration, and melting point determination were used to separate the mixture in to more pure substances. For the acid-base reaction, proton transfers occurred to result in compound polarity shifts, which allowed

Alterations: After mixing the benzoic acid, p- dichlorobenzene, and m- nitroaniline with the diethyl ether inside the separatory funnel it resulted a yellowish color with a strong odor that makes you dizzy. Preparing an hydrochloric acid solution and mixing it with the mixture of diethyl ether and there three compound creates a layer in the separatory funnel. Shaking it and releasing the gas to mix the compound very well, but too much shake trap the bubbles in the center layer that separate the organic

Extraction: Acid and Base Separation and Isolation Kaleigh Conway Chemistry 2270 Laboratory, Section 017 Instructor: Mudithangani Kolambage October 11, 2017 Abstract: The purpose of this lab was to investigate the method of extraction as a means of isolating pure compounds. In this experiment, the acid-base extraction method was used on a mixture composed of three separate components: an acid, a base, and a neutral component. The extraction solvent used was diethyl ether. Through sequential acid-base

Discussion By using acid-base extraction techniques, a three-component mixture was separated into its individual components which included an acidic, basic, and neutral component as previously mentioned. A separatory funnel was the mechanism used to carry out this procedure. Its easy handling allowed for thorough mixing of the solution. It was equipped with a stopper which was opened to release pressure from inside the funnel caused by the heat from one’s hands and also the reactions taking place

semester long experiment was to determine an unknown organic acid. An organic acid is an organic compound with acidic properties. A base reacts with acids to form salts. Titrations are used to determine the concentration of unknown substances. The purpose of the KHP experiment was to determine the molarity of NaOH. HCl titrations are mainly to check technique and used to verify the molarity of NaOH solution. The hypothesis is that this acid is C4H3OCOOH. Experimental Procedure for melting point: The

citrate salts of various metals in our daily food has to be allocated to acceptable levels; as well enforcement of these acceptable levels requires an analytical tool capable of quick, selective and sensitive detection and quantification of citric acid levels in our daily food. This analytical method utilizes a graphite sensor to determine citrate in various beverage samples. It requires the construction of a relatively simple graphite carbon electrode for the determination of citrate levels. This

In this lab, liquid-liquid extraction was performed to isolate a mixture of benzocaine and benzoic acid. 2.0107 grams of the mixture was first weighed out for the trials. When HCl was added to the mixture for the first acid extraction of benzocaine, an emulsion formed during inversion and venting that prevented a defined separation of the two layers. 8 mL of water was therefore added before continuing the extraction. The addition of NaOH then turned the top aqueous layer basic, indicated by the pH

this lab was to separate a 1:1 mixture of Acetanilide and benzoic acid through base extraction then purify these substances via recrystallization. In addition, we were able to analyze and deduce how efficient we were in purifying the substance through IR Spectroscopy, NMR spectroscopy, and by comparing melting points. This experiment proved to be partially successful. Through base extraction, we were successful in separating benzoic acid from Acetanilide. The strong base help in separating the two

the compounds in two different solvents. The objective of this experiment is to separate a 50:50 mixture of benzoic acid and benzil by using macroscale extraction. In the experiment, organic solvent diethyl ether is used. After adding 1.0 gram of the 50:50 mixture of benzoic acid and benzil to a 25ml Erlenmeyer flask, diethyl ether was added to the flask to dissolve the mixture. Benzoic acid and benzil dissolve in diethyl ether. Once the mixture dissolved in
