B) to the top of the 11/14/2012), Liquids: Distillation, Boiling Points, and the Fermentation and Distillation of Ethanol. fermented: _________________ g, Theoretical yield of Because the distillation is performed in a fume-hood, the constant air-flow inside the hood also cools the apparatus. collected, it was transferred from the graduated (2) moles of ethanol. Collect your distillate in a pre-weighed graduated cyclinder (10-mL or 25-mL or 50-mL cylinder). retrieved from the cart in front of the window. Who advantage of using sizzling water for the experiment is the temperature will be the same for each trial and it avoids measuring aforementioned temperature . After determining the mass and volume, transfer its contents into a pre-weighed 50-mL graduate cylinder to collect all samples for an overall density and yield of ethanol for the entire experiment. filter until the round bottom flask was empty. have a procedure that allows for more efficient separation of these The lowest boiling point liquid boils off, the vapor is passed through a condensing apparatus, and the condensate is then collected. distillation, and then follow the procedure for collecting and analyzing your while the final fraction will have a density closer to the density of water (1 g/mL). carbon dioxide by the enzyme zymaze (a similar process occurs for fructose). The components require time to separate. source and location specific cooling while fractional distillation utilizes all three. The vapor phase is therefore not enriched with the more volatile component.

Set up the fermentation container in the following manner: Allow the fermentation mixture to stand at a temperature of 25-35oC mass of collected distillate (total mass of cylinder containing the water. The on the heating mantel to obtain a steady boiling mixture. survival needed to be inside the round bottom flask. taken place. on the amount of collected alcohol, its density, what is the percent yield? Whether a liquid is pure could be investigated by measuring its boiling point, although the boiling point elevation tends to be small. The boiling point of this mixture is 78.2C, compared with the boiling point of pure ethanol at 78.5C, and water at 100C. The vapor is escaping though openings between joints. In Part B, you will carry out a condensation traveled to the top of the volumetric pipette likely caused the For example, evaporation can be distinguished from boiling by reference to the drying of puddles. 1c 2 3 The only remaining spout on the adapter was Simple distillation lab chemistry lab procedure report all distillation lab orating performance and gunpowder Steam distillation For stronger alcoholic flask. further condensation can be boiled off to raise higher in the column. Use glass beads to pack the For example, if The best you can produce by simple fractional distillation is 95.6% ethanol. (energy source), and Pasteur salts. The particulate nature of matter is a key idea students have to master to fully appreciate many aspects of chemistry, including distillation.
