ABSTRACT A molecular diffusion experiment was conducted with the goal of determining the diffusion coefficient of acetone into air. For this experiment‚ acetone was placed in a capillary tube and was allowed to diffuse into non-diffusing air that was passed over the test tube at the temperature of 50oC.Thetemperature is kept constant and air stream is passed over the top of the tube to ensure that the partial pressure of the vapor is transferred from the surface of the liquid to be air stream bymolecular

larger molecule. In an aldol condensation‚ β-hydroxyaldehyde or a β-hydroxyketone is produced in but upon heating the α‚β-unsaturated aldehyde or ketone with water is produced. In double mixed aldo condensation of acetone and benzaldehyde‚ the α-hydrogen’s on both sides of the acetone deprotonates and a nucleophilic enolate anion arises as a result. In an aldol condensation many products are formed there reactant are more than one thus the aldehyde reacts with itself to yield a product. The product

Biology Styrofoam cup and Acetone as Glue Submitted by: Genelive S. Galarido Submitted to: Teacher Jeannette Perez Introduction Styrofoam is the trademarked name of the plastic foam polystyrene. Polystyrene is not biodegradable and resists compression‚ making it a persistent part of landfill waste. When acetone and polystyrene are combined‚ the polystyrene dissolves. For the investigatory project‚ the student could explore the effectiveness of acetone in reducing polystyrene for

Makati Date Performed: December 5‚ 2012 Date Submitted: December 17‚ 2012 Abstract The distillation process was successfully done because of the separation of water from the acetone. When the distillate was lighted with the matchstick it produced flame which indicates that there was more presence of acetone than water. When the sodium nitroprusside‚ sodium hydroxide and glacial acetic acid was added to the distillate‚ it turned to violet. This means that there is the presence of ketone.

lab is to identify the physical and chemical properties of four liquids: acetone‚ vinegar‚ hydrogen peroxide‚ and oil. By using our knowledge about the four liquids we needed to identify the components of an unknown mixture. Theoretical Background The liquids commonly found around the house such as acetone‚ vinegar‚ hydrogen peroxide‚ and oil was tested to identify the physical and chemical properties of these liquids. Acetone usually used as nail polish remover dissolves plastic. Vinegar used in

In this laboratory experiment is stating that organic lipids have the ability to dissolve lipids membranes‚ and in this exercise acetone would be the main source to be used to have the reaction of dissolving the lipids inside the tubes. This exercise was to be able to observe how the chemicals reacted in rare temperatures such in heat and in cold weather‚ also this type of changes can create a new color either making the color lighter or darker. The reaction of a light color would be that it did

9% saline had a color intensity of .002‚ 1% acetone had .009‚ 25% acetone produced an intensity of .119‚ 50% with the intensity of .647‚ 1% alcohol had .006‚ 25% alcohol had .022‚ and 50% alcohol had .177. The highest concentration of acetone inflicted more damage on the membrane of the beetroot causing it to leak its betacyanin in a higher intensity than any of the other solvents had caused. Acetone and methanol can both cause damage to the membrane of the beetroot but acetone has a greater ability and is more damaging

Rate of Evaporation of Different Liquids Objective of the Project This project is of the rate of evaporation of different liquid‚ in which we also discuss the factors which affect the rate of liquid. Introduction When liquid is placed in an open vessel. It slowly escapes into gaseous phase ventually leaving the vessel empty. This phenomenon is known as vaporization or evaporation. Evaporation of liquids can be explained in the terms of kinetic molecular model although there

1.0 ABSTRACT In this experiment‚ our objective is to find out the gas diffusion coefficient‚ D of acetone in the air. This experiment is conducted at a temperature of 50ºC and atmospheric pressure. The method that is applied to conduct this experiment is called the Winkleman method where the level of acetone (Z) is determined every 15 minutes by using a microscope. With the level of acetone being determined‚ a graph of t/L+Lo (min /mm) vs. L-Lo (mm) is plotted and the gradient s of the graph
