Chlorine Research Paper

Chlorine is an excellent oxidizing agent. At first. The use of Chlorine was used as a bleaching agent in the paper, pulp, and textile industries and as a germicide for drinking water preparation swimming pool purification, and hospital sanitation has made community living possible. Chlorine is used in bleaching as

Backtrack to April 22, 1915. Halfway around the world in Ypres, Belgium, German forces surprise two French Colonial divisions by unleashing nearly 150 tons of pure fatal chlorine gas. Because they had never been exposed to chemical warfare on a scale like this; The French forces had no protection against this deadly toxin. This lack of preparation sent front line troops into a panic. Nearly 6,000 troops were killed because of the deadly gas. These soldiers did not die peacefully, as they choked and burned to death as if they were parasites. The Germans, who bombarded “No man’s land” and the front line trenches with the chlorine gas were equally as surprised with the devastation the unbeatable gas left. Long story short, although German forces had a major advantage with this toxic new weapon; they failed to come out of the Second Battle of Ypres with a victory. Shortly after worldwide mass production of gas masks were being put into effect for the war. This first use of chemical warfare changed the entire

Chlorine was first discovered by a man whose profession was in the medical field. However, since it was 1774, the technology wasn’t as advanced and therefore led him to misleading conclusions. Carl Wilhelm Sheele was a Swedish pharmacist who, “released a few drops of hydrochloric acid onto a piece of manganese dioxide in his lab, and a greenish-yellow gas was produced in a matter of seconds…” (Alchin, Linda. “The Element Chlorine.” What Is Chlorine?, www.elementalmatter.info/element-chlorine.htm.). Before Sir Humphry Davy, people thought that Chlorine was a form of oxygen. Sir Humphry Davy later proved otherwise. Although this element was never thought to be used this way, in World War I Chlorine was used as a “choking agent”. Men would suffer

This week I learnt about chlorpromazine, which is an antipsychotic. It is also used in short-term management of anxiety, agitation or disturbed behaviour in non-psychotic disorders. Chlorpromazine is an antagonist of many receptors, which include α1 adrenoceptor, M3 muscarinic receptor, H1 Histamine receptor, 5HT2 receptor, dopamine D2 receptor and angiotensin II AT1 receptor. This illustrates one of the pharmacology principles, which is selectivity of a drug. A highly selective drug (‘clean drug’) binds to only one receptor or molecular target whereas a drug having low selectivity (‘dirty drug’) will bind to many targets in the body. Binding upon many receptors can produce many effects but some effects are not desired. For example, chlorpromazine

Society during 1800’s was vigorous due to the comparison of risk to use chloroform, with women being Snow’s main target in research there was still confusion amongst pubic. Despite this religion had mixed views about chloroform, some would refuse its use and others had no reasons for their opinion but some had no concerns due to the Queens uses. A few religions views were supported by media, whereas others supported Simpson’s views and medical support was similar in the way of split views of chloroform, but was widely discussed but some medical leaders believed chloroform was unethical. The Church of England preached the uses of chloroform, but because of the Queen’s uses their views changed because of the success. In the 20th century, chloroform

Whether it’s kinetics, flying, invisibility or mind reading, super powers is something that humanity has been striving to obtain long before we can even recall. With science and technology moving forward, what once seemed just a fantasy is shaping into something more possible now. Scientists all over the world are working on various ways to create a better, more advanced “model of human”.

Chlorines history was never intended to be used as a weapon. In 1774 German-Swedish chemist Carl Wilhelm Scheele discovered the chemical (Chlorine, 2013). The uses for liquid and solid chlorine was found to kill bacteria and has been developed to be used in small quantities to

Another kind of incident that occurred before when Ken should've done something when he had the chance was when David sniffed chloroform. This substance, chloroform, was known as a very dangerous substance to have around your house. A chloroform is a, “primitive anesthetic commonly used during surgery in the mid-18002”(silverstein 17). Chloroform was initially used to make people sleep so they wouldn’t feel the pain of surgeries. It could be dangerous if you sniff it a lot. But David didn't care about that. Reading his favorite book, the golden book, it, “urged readers to sniff carefully…David took the challenge, but apparently sniffed too vigorously and ended up flat on his back. He estimated he was out for more than an hour”(Silverstein 17).

Chlorine has an atomic mass of 35.453, atomic number 17, is a member of the halogen family (VIIA), and its symbol is “Cl”. Chlorine contains 17 protons and 18 neutrons in is nucleus. There are two isotopes for chlorine as well; Cl-35 and Cl-37. Chlorine was discovered in 1774 by Swedish chemist Carl Wilhelm Sheele. Sheele came upon chlorine when he put a few drops of hydrochloric acid (HCl), then known as muriatic acid, onto a piece of manganese dioxide (MnO2). This caused a reaction where the pricduct was a yellowish-green gas that would later be named chlorine. At this point Sheele thought that this gas contained oxygen and was some sort of oxygen compound,

Chlorine can get into our eyes through releasing of chlorine gas into the air which is one way chlorine gets into our eyes. Another way is through contact with water that contains a lot of chlorine. The moisture that is present in the eyes when in contact with chlorine tends to form acid and causes more irritation. 4.1 DISTRIBUTION Chlorine as mentioned is absorbed in the body through inhalation, ingestion, drinking, skin contact, and as well as eye contact.

If an element is high on the table, it indicates that it is very reactive. Meaning chlorine is more reactive than bromine, iodine and astatine.

First of all, tetrachloroethylene is a nonflammable colourless liquid which goes by with the formula C2Cl4. Tetrachloroethylene is a reaction between two elements: chlorine (Cl) and carbon (C). This reaction raises a lot of concerns since it is mainly used for dry-cleaning fabrics and metal degreasing operations. Firstly, the exposure to tetrachloroethylene has many negative effects on the health of humans and the environment. Effects that develop from severe (short term) high-level intake exposure of humans include the irritation of the upper respiratory tract and eyes, kidney dysfunction, and many neurological effects such as behavioral changes, impairment of coordination, dizziness, headaches, sleepiness as well as unconsciousness. The effects

An initial amount of chlorine is reduced to chloride by the reducing agents present, and

Chlorine-36 ages (Paterson et al., 2005) show a progression with distance over the Dakhla Basin eastward from 210-230 kyr in Dakhla reaching ~600 kyr in Kharga and northeastward to 320 kyr in Farafra and 700 kyr in Bahariya (Fig. 5). 36Cl/Cl ratios vertically indicate long, deep flowpaths of the paleorecharge near the southern highlands of the Uweinat area. Late Quaternary recharge appears to affect the shallow aquifer horizons only (Paterson et al., 2005).

Blame chlorine as one of the chemicals used to treat and purify drinking water. The water of today also contains contaminants that are potentially dangerous to use for you and your family. Your
