Isolation Of Fluorine Lab Report

Hydrofluorcarbons (HFC’s) are a new class of recently developed propellants, they share many of the same properties as CFC’s but are less polluting. Several popular HFC’s include 1,1-difluoroethane and 1,1,1,2,-tetrafluoromethane. These propellants are relatively expensive but formulate fast drying. Currently the most commonly used propellant is dimethyl ether (DME).

Fluorides are compounds that have been combined with the element fluorine with another substance usually a metal (Cancer.org 2015). Fluoride is a naturally occurring element found in rocks, in soil everywhere, in fresh water and in ocean water (Fluoride information network 2015). Fluorides strengthen teeth already present inside the mouth. Once in the digestive tract they travel through the blood to areas with high

Also, fluoride has long been known as a toxic substance. This is the reason that it has been used in pesticides and rodenticides and now

Are you aware that fluoride that is used to help keep teeth healthy is actually a harmful compound. The number of products that contain fluoride is actually quite high. Many people may not know it is also in our drinking water. The scary thing is fluoride is now classified as a neurotoxin.

Fluoride is the ionic form of the element fluorine, different in chemical and physical properties. It is most usually used in compounds for industry, however, it can be added to water sources. Few areas in the UK have fluoridated tap water, providing them with key nutrients needed by the body and an efficient method of preventing tooth decay. On the other hand, there has been speculation linking fluoride to certain disorders and diseases which has caused concern within the country.

Although fluorine is not the nicest or easiest element to work with, it still is an overall benefit to society. It has helped the dental industry in the form of fluoride and has many practical everyday uses in the form of compounds. Fluorine is also beneficial to the solidity of our bones (“Lenntech”). All in all, fluorine typically lives a crazy and wild life as a pure element, but helps to serve the world when mixed with other elements that help keep it in

Super fluorine symbol is F and shines the letter F up in a dark night sky where the brightest stars are. To make them pop out so everyone in the city of New York knows he is here to save them from nasty bacteria. Fluorine atomic number is the number nine. Fluorine is originally a pale yellow. He came from outer space from a low mass star’s epic death. The low mass star life cycle was to the end moreover, now it's a white dwarf. Low Mass star begin their life with a stellar nebula then an average star, next red giant, second a planetary nebula. Lastly a white dwarf moreover, the end if its life cycle. Super fluorine is rare to see him in the universe, but he is the thirteen most common element in the earth's crust. He pops out of the ground

Fluoride is an artificial waste product of nuclear, aluminum, and phosphate fertilizer companies. Fluoride has the ability to combine and increase the toxicity of other toxic materials. Fluoride acquired from industrial waste and added to water supplies it is also polluted with lead, aluminum, and cadmium.

Fluoride happens to be one of the most abundant elements on the earth’s crust, the 13th most abundant in fact. It’s a chemical ion of the fluoride element and has a single extra electron, giving it a negative charge. It’s found naturally in the soil, in our water, our food as well as several other minerals including fluorite. The concentration of fluoride within our seawater would appear to average at around 1.3 parts per million or ppm. In fresh water however it naturally ranges anywhere from 0.01ppm to 0.3ppm, though there are parts of the world that are subject to fresh water with dangerously high amounts of naturally occurring fluoride and as a result, health issues arise in later life.

Fluoride has been linked in government and scientific reports to a wide range of harmful health effects, including: bone and tooth decay (including dental and skeletal fluorosis, bone pathology, arthritis, and osteoporosis) Alzheimer's, memory loss and other neurological impairment, kidney damage, cancer, genetic damage, and gastrointestinal problems. In addition, fluoride has been found to leach lead from old water pipes and soldering material, which has resulted in increased lead levels in people.

Fluoride is an ion which comes from the element fluorine (9th on the periodic table). It’s an abundant element found in the Earth’s crust and it is never found in its free state in nature. Rather, “fluoride only will exist in combination with other elements, in compounds such as Sodium fluoride or Sodium fluorosilicate” (NSW Health 2015). The naturally present fluoride in water combines with these other elements as water passes over or through rocks and minerals. Typically, underground water sources, such as the aquifer, will have higher levels of fluoride than surface water sources such as rivers and lakes. Across the United States, the “natural levels of fluoride can vary between very minute quantities to over 4 mg/L” (ADA 2005). In addition,

For instance, in a single oral dose of soluble fluoride at 60 mg/kg without calcium intake causes acute heart failure and about 25 PPM fluoridated water can lead to chronic heart failure. (Sauerheber, 2013). Systemic fluoride may cause atherosclerotic plaque in coronary vessels of patients with a cardiovascular disease. In addition of that , it can be accumulated in aorta and the calcification will occur in that artery because the concentration is increasing with age. Many kidney dialysis patients died from a high fluoride level in the fluoridated drinking water because dialysis units can not extract fluoride from blood. (Ahmad, 2005, Cited in Sauerheber, 2013). Moreover, industrial fluoride in water supplies can cause gastrointestinal distress and pain because of HF formed from fluoride. HF prevents tissue healing and cause a structural damage to mucosa at 20 PPM in 15 minutes. (Petraborg, 1977, Cited in Sauerheber, 2013). The only proven harm effect resulted from the usage of fluoride in dentistry is Dental Fluorosis which can be defined as a dose-response effect as a result of excessive use or ingestion of fluoride during the pre-eruptive stage of teeth development. (Browne, 2012). Dental fluorosis ranges from normal in which the fluoridated enamel is still smooth, glossy, fully functional and has white translucent surface to the severe dental fluorosis stage when all the

In this world we face obstacles in a daily manner. With this we are focused mainly on these obstacles, leaving us vulnerable to certain aspects. Behind each line of this society, there is a well kept secret. The most critical secret that is kept is arguably the effects of fluoride.

The intake of fluoride in excess can contribute to health issue known as fluorosis, which could be unethical due to adverse effects“Severe cases can be caused by exposure to water that is naturally fluoridated to levels well above the recommended levels, or by exposure to other fluoride sources such as brick tea or pollution from high fluoride coal.” On the other hand, however it can cause negative effects such as tumour, thyroid damage, bone issues and effects to the mental wellbeing.

Fluoride is one of the important heavy metal present in water and waste water. Fluoride ions in water exhibits unique properties, as itsoptimum dosein drinking water is advantageous to health and excess concentration beyond the prescribed limits affects health(5). Also Fluoride ions are extremely toxic to human body. A fluoride ion is attracted by positively charged calcium in Teeth and Bones, due to its strong electronegativity. Major health problems caused by fluoride are dental fluorosis, teeth mottling, skeletal fluorosis, and deformation of bones occur in children as well as adults (5). The waste water also containing high concentration of fluoride ions that may discharged from mines, semiconductor factories, and
