Simple Distillation: A Test on the Amount of Ethanol Present in Vodka By: Morales, Michah A. Ogsimer, Juk Rances F. Pacia, Carissa Jenelle Y. Panganiban, Aean Genesis R. Rabang, Maika I. 2B-Medical Technology, Faculty of Pharmacy, University of Santo Tomas ABSTRACT Distillation is a technique in separating two liquid components. There are two types of distillation used in this experiment known as the simple and fractional distillation. The objective of this experiment was to be able to determine

Introduction (Experiment 1) Distillation is a process involving the conversion of a liquid into a vapor that is later on condense back to liquid form for collection of distillate. It is used to separate the components of a liquid from non volatile solids or those liquid having different boiling points which will be seen on this experiment. (Abdullah, M.G. et. al (2013, December 15) distillation. http://www.britannica.com/EBchecked/topic/166098/distillation) This method is used to purify a liquid

key findings, main significance, and major conclusions. This information helps readers decide whether they need to read the whole report. Sample Abstract This report presents the separation of a 10%mol ethanol-water mixture with a 28-stage distillation column. Both finite and infinite reflux runs were performed, each at a high supply steam pressure (80 Kpa) to the reboiler and at a low pressure (70 Kpa). Murphree and point efficiencies were calculated for the active stages sampled after steady-state

Azeotropic Distillation of water and ethanol by Harold van Schevensteen The process of simple distillation is a method of separating mixtures based on their differences in volatility in a boiling liquid mixture. We find out, however, that using this process, a mixture of water and ethanol cannot be separated fully. The latter can only be purified to approximately 96%. To get to this point, we go through a process whereby through distillation, we reduce the proportion of water in the mixture

container). There is one spray top per group (use it with the boiling tubes). Start with the lowest concentration of pesticide and work upwards. The spraying of pesticide must be carried out in the fume hoods. Briefly spray the pot through the mesh netting so that the pesticide comes into contact with the flies. Before spraying make sure none of the flies are on the netting, as otherwise they will get a larger dose than those on the bottom of the container. You should also use the same procedure

Distillation of Water Distilled water is water that has had many of its impurities removed through distillation. Distillation involves boiling the water and then condensing the steam into a clean container. Distilled water finds its use in a wide range of applications where the natural dissolved salts that water normally contains are not desirable. Some of these are topping up lead acid batteries, preparing aseptic solutions in hospitals, automotive cooling systems, steam irons, etc. Distilled water

Without using electricity, there are many ways to illuminate a parking lot. First, I can decorate the ceilings and walls of the parking lot with glow sticks (light sticks). This method of producing light is called chemiluminescence. Chemiluminescence is the direct production of light as the result of a chemical reaction with little or no heat produced. The glow sticks can operate by causing two chemicals to mix. A common reaction used for these devices are hydrogen peroxide and phenol oxalate ester
