Boiling

the bacteria, viruses and protozoa that may be lurking in the water, completely invisible to the naked eye. Boiling water will not kill or neutralize chemical contaminants. The water doesn't have to boil 10 minutes. As soon as you see the bubbles on the surface, the water has become hot enough to kill the various contaminants. Boiling for 10 minutes is a waste of water. Dead is dead and boiling the water longer does not kill the harmful bacteria and what not any better. Solar Purification If…

We also enjoy partying and having fun! Every year on good Friday our family would gather around and have a crawfish boil. It was like our own tradition. We would eat crawfish because we couldn’t have meat on good Friday. Now I hadn’t perfected boiling crawfish, so usually…

it out and it’s simple; they haven’t reached 212 Degrees yet. Did I lose ya? Well think about what happens when you boil water. At 211 degrees the water is very hot but it’s not boiling because it must heat up one degree hotter to start boiling. Why is that important? Well for starters think about what boiling water can do: It creates steam and steam can power a locomotive. Not so with 211…

then be feed to the next part of the operation which is purification. In two different distillation columns, Methanol is purify to achieve the product quality which is required. In the first column, low boiling impurities known as light ends are removed. Light ends are materials that have a lower boiling point than Methanol. When heated, these materials will boil before Methanol. These unwanted impurities can be seperated out from the top of the column by…

1, on the burner. 9. Take test tube number 2 and put it in beaker number 2, on the burner. 10. Monitor the temperature of test tube number 2. (The water must stay at 70oC take on and off burner as needed) 11. Test tube number 2 needs to be at a boiling temperature. 12. Once the water is correct, let both test tubes 1 and 2 sit for 14 minutes. NOTE: At this point you should have test tube numbers 3-8 left. 13. Take test tube number 3 and place it in beaker number 3 which should be still room…

By using the techniques of simple distillation and gas chromatography to purify and determine relative proportions of volatile compounds in their gas form. Distillation could be described as a process where a mixture was heated until it began to boil, and the condensed vapor was collected. After completing the distillation process, the gas chromatography method could be used to identify the relative components of a compound in a volatile mixture. According to the analysis between the…

plastic funnel. Three milliliter of tert-butyl methyl ether and two or three boiling chips were added into the flask. The black plastic connector was used just like the distillation column with air condenser set-up. The flask was clamped to the ring stand using 3-pronged clamp. The flask was lowered into a slightly depression in the sand without touching directly to the sand. The mixture was then boiled gently at the boiling point for 10 minutes, removed from the heating, and settled for a…

had a mean and standard deviation of 44 sec +- 6.48 seconds, and the Catalase in the 103 degree Celsius test had a mean and standard deviation of 240 +- 0 because the reaction never happened for this test. The hypothesis was rejected because the boiling temperature actually denatured the enzyme and prevented it from causing a reaction. The body temperature test proved to have the best effects on reaction time it had the lowest mean at 44 seconds. The results showed that the enzyme, Catalase,…

Measured with a digital scale with at least 2 decimal points. Dependent Variable The mass of DNA extracted from kiwi (Grams) Use a spatula to extract the DNA from boiling tubes and a beaker on a tarred digital scale to hold and weight it. Variable Measured Variable Measuring Method Reason for Measuring Controlled Variables Mass of Salt in the Extraction Solution 0.5 grams of salt is used for each set of extraction…

smooth boiling. In this experiment by adding the anti-bumping granules we were able to achieve smooth boiling throughout both the reflux process and the distillation process. Without adding these granules, bubbles of vapour may be difficult to form due to both process being conducted in a very clean, smooth glassware. Then all of a sudden a large bubble may form and disturb the liquid violently. Therefore the anti-bumping granules help prevent this ‘bumping’ which may disturb the boiling process…
