Separatory funnel

Isolation of Component Via Extraction Objective: Separation of organic acid from a neutral compound using liquid/liquid extraction. Experimental: Similar to the “Thin Layer Chromatography” experiment, a TLC plate was ran with 2 ml of EtOAc and 8 mL of hexane in the jar. The Rf value was calculated using the formula located in the data for all the TLC plate. The mixed compound that was dotted on the TLC plate had 0.300 g of the impure benzoic acid and 10 mL of dichloromethane. A 50 mL flask was weighed and recorded. A separation funnel was then filled with 10mL of 3M NaOH and 10 mL of the dichloromethane. The funnel was capped and flipped upside-down while the lid was held. The solvent was mixed inside the separation funnel for a couple…

Abstract: The objectives of this lab are relatively simple: using a separatory funnel to separate a pure substance from a mixture, determine the mass of a sample of caffeine using mass spectrometry, and as a way to separate compounds, use gas chromatography. Using gas chromatography and mass spectrometry you are more accurately able to determine the sample of caffeine. Amount of Caffeine in 100mL sample of Coffee. Introduction: Within this lab, our group was supposed to determine the amount of…

Mixture #6 - Beaker Tongs - Funnel - Scoopula - Wire Rack - Filter Paper - Balance - Stir Rods - Beakers - DI (deionized) water - Drying Oven - Weigh Boat Procedure: 1. Measure all of your equipment and record the mass onto the data table. a. Subtract the mass of the piece of equipment that is being used to hold the substance from the total mass. b. Make observations on a sheet of paper. 2. Use a stir rod to mix the three substances that are in the beaker. 3. Measure the mass of…

daring to meet my attacker only suprised to see King Bellicus behing me. “Going somewhere are we?,” he asked as he arched his eyebrow at my duffel bag. “I was hoping to discuss why you fled so early from my advisors, surely you are one usually to make your opinion heard. Do you know anything of this shadow realm?” “There are tales of black magic in the woods, that Trepido is arming an attack, maybe they are trying to shake you up…” It was coming a funnel cloud of black swirling right in my…

The extraction lab began with a .517g mixture of benzoic acid, p-nitroaniline, and azobenzene charged in a 125 mL Erlenmeyer flask mixed with 50 mL of Et2O. Once dissolved, the mixture is transferred the mixture into separatory funnel and begin acid extraction. 15 mL of 3 M HCl is added to the separatory funnel and inverted until a phase boundary is present. An additional 15 mL of 3 M HCl was then added and inverted again. The aqueous layer was removed through the separatory funnel and placed…

ether. Since ethyl ether and water are insoluble in each other, they will form two phases and can be separated from each other using a separatory funnel. The reacted organic compound…

Introduction In this experiment, the goal was to isolate an organic substance. Using extraction, a basic, acidic, and neutral substance was expected to be extracted from the original unknown compound. Extraction is a process that allows the separation of substances that were previously mixed together through the use of a solvent1. This can be useful in situations where the substance has both the desired product and undesired byproducts in it. In order for extraction to work, the solvent must…

Procedure: Part A: Extraction stage 1. Place a 125 mL separatory funnel in a ring stand equipped with a small ring. 2. Heat the hot plate. 3. Heat the water (20 mL of hot water is needed) to a boil by placing it on top of the hot plate. 2. To the 125 mL Erlenmeyer flask, added two Tylenol (500 mg/ tablet) 3. Dissolved the solid by gently swirling the Erlenmeyer flask. 4. Let the solution cool for a few minutes (approximately till room temperature). 5. Add the mixture to the separatory funnel.…

To carry out the experiment we need to get caffeine into a solution. We used a solid-liquid extraction by adding 14 tea bags into a 1L beaker with 6g of sodium carbonate, 250 mL of tap water and bringing this to a boil for five minutes on a hot plate. Sodium carbonate is a weak bronsted base, that neutralizes tannic acids extracted from tea, that interfere with the later sublimation operation.(1) We turned the heat off after five minutes, added ice cubes to cool the mixture to room…

process by which a three-component mixture was separated and identified. The mixture was separated with the aid of a separatory funnel and various solvents acids and bases. The compound was found to be comprised of meta-nitroaniline, naphthalene, and benzoic acid / 2-napthol. All three of them are organic compounds with melting points in the order they were listed 111-114, 79-82 and 121-122/121-123 °C. the percent yield of each component was also calculated at the end based on the initial…
