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

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

-------------------------------------------------------------------------------- With Calcium Hypochlorite and Acetone When chlorine is passed into boiling alcohol‚ both chlorination of the methyl group and oxidation of the primary alcohol group to an aldehyde occur‚ giving trichloro-acetaldehyde or chloral: When chloral is treated with caustic alkali‚ fission of the C-C linkage occurs‚ giving chloroform and a formate. Acetaldehyde and also many ketones‚ such as acetone‚ containing the CH3CO- group behave similarly when treated with calcium

molten polystyrene into Styrofoam through the construction of a porous cellular structure. The organic compound (CH3)2CO‚ or acetone‚ is a translucent flammable liquid that exhibits a high degree of solvency. Many compounds are soluble when exposed to acetone. A Styrofoam and acetone experiment can determine if Styrofoam will dissolve when placed inside a container of acetone. Starch is the major component of flour. Starch exists in tiny granules‚ which swell and break when boiled in water. This

Intrinsic Viscosity Introduction One of the most precise measurements in polymer science is also the simplest and cheapest. Intrinsic viscosity‚ which is measured from the flow time of a solution through a simple glass capillary‚ has considerable historical importance for establishing the very existence of polymer molecules. It also provides considerable physical insight. In this lab‚ each group will study the intrinsic viscosity of hydroxypropylcellulose‚ a common polymer derived from cellulose--hopefully

I hypothesize that the higher % of the solvent that the higher the colour intensity will be shown on the ph colour scale. The lower the solvent then the less colour shown. Materials: *Test Tubes (4) *Cork Borer *Beets *Water *1% Acetone *50% Acetone *1% Methanol *50% Methanol Procedure: *Cut 4 uniform cylinders of beet using a cork borer with a 5-mm inside diameter. Trim each cylinder to 15-mm in length. *Place these cylinders of beet tissues in a beaker and run tap water over

mixture of hexane and acetone was determined to best solvent for this extraction. Knowing this add one mL of the pure hexane and one mL of the pure acetone to the mortar. Grind the contents until the cell walls have been adequately broken. Transfer the mixture to a centrifuge tube to separate the sample into layers‚ to help remove the water. Once the sample is finished spinning extract the organic layer and place in a test tube. TLC: To determine which mixture acetone and hexane is the best

Abstract The chloride present in an unknown soluble sample was precipitated into silver chloride through precipitation gravimetry. The colloidal silver chloride originally formed was converted to a crystalline solid by controlling certain parameters of the experiment such as temperature‚ pH of the solution‚ and concentration of AgNO3. Once the solid was large enough‚ it could be washed‚ filtered‚ and weighed. The percentage of chloride present was found to be 24.73695223 (±0.00000006) %.
