performed a fractional distillation set-up. At the end of the day‚ they were able to attain the following objectives: differentiate simple from fractional distillation‚ separate the components of an alcoholic beverage and calculate the percentage of ethanol in a beverage. EXPERIMENTAL A. Compounds tested The compound or sample used in this experiment was vodka (alcohol). Vodka (35%–50%) was originally distilled from fermented wheat mash but now also made from a mash of rye‚ corn‚ or potatoes

3.1. Biochemical analysis of plant Due to the presence of bioactive compounds‚ medicinal plants have special properties of treatment of various chronic diseases. Lonicera quinquelocularis is used medicinally in the treatment of different diseases as “alternative medicine”. Due to the medicinal uses of the plant‚ it is very important to explore the biochemical composition of the plant. 3.1.1. Plant Collection Plant of Lonicera quinquelocularis was collected from the area Kakki of district Bannu‚ Khyber

about alcohol‚ risk factors will likely decrease. Everyone should understand just exactly what alcohol is‚ as well as how the body reacts to consumption. Alcohol is another name for the chemical compound ethanol‚ which is produced by the fermentation of yeast‚ sugars‚ and starches (NIDA). Ethanol is a depressant‚ meaning that shortly after it is consumed‚ it will begin to slow down the central nervous system (NIDA). The central nervous system controls functions such as reaction time‚ balance‚ and

behaviour? What is going on? “Drink driving is usually defined as driving with a specific amount of alcohol in the blood‚ known as an individual’s BAC – which can be measured from blood‚ urine‚ and breath tests that estimate the number of grams of ethanol per 100ml of blood.” (Reference: article 1) How is the behaviour performed? When? Where? Drink driving is performed when an individual drives a vehicle whilst over the legal BAC limit of 0.05 and 0.00 for Provisional drivers. It can be performed

Discussion and Interpretation of Results The addition of HBr to 1-hexene created a 2-bromohexane‚ as indicated from the ethanol silver nitrate test and sodium iodide/acetone test. The observations when the product was subjected to these tests were similar to what were observed with the 2° bromide compound. When subjected to the silver nitrate test‚ the product produced a precipitate at the same rate of the 2° bromide compound‚ and the product produced a hue of yellow that was also similar to the

Recrystallization is of key importance in the experiment because this method is used to obtain the crystals. Recrystallization is a purification technique that removes impurities from a sample. An impure solid is placed in a liquid for example water or ethanol. It is then heated making the solid dissolve into the solvent. When the solvent cools back down again‚ the solid will precipitate out of the solution and leave the impurities behind‚ still dissolved in the solvent. This method purifies the solid.

Experiment 3. Colours in Kool-Aid Abstract Tetramethylammonium iodide was dissolved in a mixture of of Iodine and 95% ethanol while gently heated in a fume hood. Once cooled‚ crystals started to form in the beaker‚ which were then collected and washed with hexane through a series of processes involving vacuum filtration. Then a mixture of 5mh of the crystals and 5ml of 95% ethanol was created and tested on a slice of potato to analyse the iodine content. After‚ with sodium thiosulphate in the buret

applications‚ fermentation has proven to be an economically and commercially viable mode to produce alcohol. The type of alcohol that is commonly extracted through this process for the food industry is known as ethanol‚ which in its purest form would be harmful for consumption. Thus‚ ethanol is always mixed with other substances to render it safe for
