The instantaneous rate at which oil can be extracted is 14% of the amount of oil remaining per year. The 42 percent yield was most likely due to side reactions occurring in the flask. Condom, Friction, Latex 721 Words 4 Pages tapings before taking down the readings and make sure that we avoid parallax error by ensuring our eyes is leveled with the tapings when recording the readings. Water, sodium bicarbonate, and sodium chloride were used to extract any impurities from the product. A complex salt is an ionic compound but it differs in the fact that there are these covalent bonds attaching the metal to the ligand. The literature value most likely used a mercury thermometer, while the experiment performed used an alcohol thermometer.

It controls the traffic of materials in and out of the cell. Two factors that affect the ability of a solution to form are: 1 the natural tendency of substances to mix and spread into larger volumes when not restrained in some way 2 the types of intermolecular forces in the solution. The liquid turned dark brown when the polymer formed. This confirmed that we in fact had banana oil as our final product. Place the reaction mixture in a separatory funnel and add 55 mL of cold water remember to rinse the reaction flask with 10 mL of cold water and add it to the separatory funnel. Tubing to cool the condensor column is attached so that the water enters the column at the lower nipple and exits the upper nipple connector. Drain the aqueous layer, and leave the organic layer in the separatory funnel.

Synthesis of Isopentyl Acetate (Banana Oil)

banana oil lab

This work by Fischer led directly to proving the existence of the asymmetric carbon atom, a concept proposed by Van't Hoff and Lebel in 1874. Microorganisms are found throughout the environment: in the air and water; on the surface of any object such as clothes, walls, furniture; in soil and dust; and on and in our own bodies skin and mucous membranes. Hydrolysis is the breaking of the ester apart back to the acid and the alcohol. This is a good yield for the experiment. The point where the bottom of the condenser wet portion and the top of the condenser dry portion converge is called the.

The analysis continues where the mass of the anhydrous salt is determined. Acetic acid, Carbon dioxide, Distillation 1406 Words 5 Pages © Professors Kathleen V. Repeat the procedure with each lubricant and using a new condom. Using the molecular weight of the molecules of isopleths alcohol and acetic acid we found the moles of each molecule. The families from the infants would collect their water from wells.

This report discloses the basic laboratory instruments will be used in each of our practices. Give more details of the many causes for obtaining less than 100% Yield. The flask was weighed again to determine the final product after the nitrogen was blown over the solution after the another. To test Mariotte's Law 2. Changes of copper complexes when various are added and filtering out the precipitate by using Buchner funnel for vacuum filtration. Extract the organic layer upper layer with 25 mL of 5% sodium bicarbonate solution twice test to be certain that the aqueous layer is basic to litmus otherwise wash again. If it is caused by impurities, there is only a trace amount.

Once we found that isopleths alcohol was the limiting reagent, we found how many grams of banana oil were possible to produce. She gives an equal amount of banana bread to 5 friends. After the reaction, the solution is washed with sodium bicarbonate. Discuss whether this experiment is a good example of Green Chemistry. The moles for acetic acid were calculated at 0. This meant that we successfully removed all the excess alcohol from our mixture. As we had our final solution of banana oil, we used the I.

We removed all that was available and then began to add sodium carbonate to help wash and dry the mixture. Both extraction and distillation were employed to obtain a pure product. Three fields of study are composed within this memo that includes Electrical Engineering, Environmental Engineering, and Petroleum Engineering. Data Tables: Data Table 1: Food Item - Observations. Sodium Bicarbonate is added but the question doesn't say anything about it. Alternating current, Electrical impedance, Electrical resistance 1576 Words 6 Pages Lab Report: Halogen Reactions Purpose: This experiment will allow for exploration into some of the properties of Group 17 elements halogens and their compounds.

During the distillation, the temperature was recorded for the boiling point of isopentyl acetate. You need to explain what substances should have been in the flask at the end of refluxing. . Both liquids were combined and remained clear until the addition of concentrated sulfuric acid. To predict the solubility of an unknown Group 2A salt based on the determinations made. I don't know what kind of an answer the teacher is looking for.

We verified our answers using infrared spectroscopy. The instantaneous rate at which oil can be extracted is 14% of the amount of oil remaining per year. Stop the distillation when only a drop or so of liquid remains in the pot or when the temperature reaches 143%. Chemistry, Concentration, Copper 839 Words 4 Pages. There is a possibility that this number would have been larger.
