An element in chemistry is more than just an element; at least Chlorine is more than just an element. It is very useful in many ways that help people today. Chlorine is a common nonmetallic element belonging to the halogens; it is a heavy yellow irritating toxic gas; it is used to purify water and as a bleaching agent and disinfectant; occurs naturally only as a salt. People should know more about the uses of chlorine and why chlorine is used in many processes, for example; bleaching, and why we use it today. Everything has to start somewhere, and chlorine was produced many years ago.
Not many people know when and by whom chlorine was first produced, when it was given its name, or what it is used for today. Chlorine was first produced in 1774 by Swedish pharmacist Carl Wilhem Scheele. In other words, the thirteenth century. Chlorine was given its name in 1810. Chlorine is used as a disinfectant or bleaching. “Chlorine is used to fight against a wide array of life-threatening infections, viruses, and bacteria for over 150 years” (Chlorine Element). Chlorine is used in swimming pools to keep them clean and free of bacteria. “Chlorine is used as bleach in the manufacture of paper and cloth; and before that chlorine was used in World War I as a choking (pulmonary) agent”(Emergency). There are many health effects of chlorine that are very traumatic in some cases.
When exposed to chlorine no one can ever know how badly someone is exposed to it until that person starts to experience the effects of chlorine. Some effects of chlorine are hard to differentiate from for example a cough or sore throat. “When exposed to chlorine someone may experience coughing, or chest pains, which is affected with only small amounts of chlorine

Scientists have learned the effects of chlorine, how someone is exposed to chlorine, how it is used today, how to protect oneself from being exposed to chorine, and when chlorine was first discovered. Chlorine is a nonmetallic poisonous gas that can change someone’s life just by them catching a whiff of the chlorine. It is hard to tell what new discoveries about chlorine will be found, but I believe the excitement is in the process of waiting for the new discoveries to come about.

Chemists are the specialists in chemistry, that interact with chemical properties, and reactions. The earth is made up of different gases. Some of this gases are needed for life in the planet but other gases can be harmful to the living. Gas’s use in regular quantities are favorable to the earth. The world started to become more advance and had to use more of this gases to produce everyday objects and inventions by men. Little did we knew this chemicals we going to affect us in our life. Chemist Jose Mario Molina actually discovered that chlorofluorocarbons were affecting the ozone layer.
Green Chemistry is not only used in the lab when handling dangerous chemicals, but is also used in everyday life. Some areas where green chemistry may be applied is in medicine, biodegradable plastic, and paint. Pharmaceutical companies are always looking for better ways to make medications have less side effects by making them produce less toxic waste. Also, more and more companies are trying to create products that use compostable or biodegradable materials. Paints usually have toxic fumes that go along with them. Some painting companies are trying to create a product that emits less toxins to better human health and environmental
Although some of the elements have been known for thousands of years, our understanding of many elements is still young. Mendeleev’s first Periodic Table contained only 63 elements, and about that many were discovered in the following 100 years. Just like countries, emperors, philosophers, and cities, elements have histories, too.“The Disappearing spoon” by Sam Kean, is a detailed history of the elements on the Periodic Table. Kean does a important job of telling every single element’s journey throughout the history of mankind: from the earliest times, when chemistry was intermingled with alchemy, to these days of modern chemistry. For example: Thallium is considered the deadliest element, pretending to be potassium to gain entry into our cells where it then breaks amino acid bonds within proteins. The CIA once developed a plan to poison Fidel Castro by dosing his socks with thallium-tainted
These applications include pesticide, herbicide, defoliating agent such as Agent Orange, cleaning agent and electrical insulation. Consequently, human exposure to dioxin is not a recent phenomenon and the dangers of dioxin are not unknown. Only in recent years, especially after the Vietnam War, has the media concentrated on the dangers and impact of dioxin. The physical effect of exposure to dioxin was first seen in skin diseases developed by chemical plant workers in 1895. Exposure to dioxin results in a type of skin disease like acne called "chloroacne," since its cause was initially and incorrectly linked to chlorine gas.
Every year, there are about 100 million Sharks killed, ultimately for its commercial success. Their fins are used as the main ingredient for a dish so-called Shark soup. However, many are unaware of the actual importance of Sharks' existence on Earth. They do a number of things to control and balance aquatic life down below, which in return affects how we live on the surface. Sharks have existed in our world for over 400 million years, if they were to suddenly disappear for industrial purposes, much problems will be encountered throughout the world. We must preserve the lives of Sharks, for many reasons most importantly that shark hunting is morally wrong, it may provide economic failure in a given time, and it may serve a critical unbalance of a healthy environmental state.
23 April 1915 British troops were attacked with chlorine gas, and Sir John French, the British Commander-in-Chief wanted retaliation with the same effects that was dealt to his troops, and he also wanted the means to defend his troop against these attacks, which lead to the establishment of Porton Down. 10 July 1915 the British used chlorine gas against the Germans, after the attacks the British realized that the chlorine delivery method was inconsistent, the gas had a small radius of cover, the chlorine had a smell so it could be detected early without inhaling a large amount, and the gas also didn’t stay on the ground very long, so further research went into the development of chemical weapons. The first experiment was done with hydrogen sulphide; the British tested the gas by placing rats in cages in trenches, and had mine workers with self contained breathing apparatus collect clouds of the gas in jars as the gas passed over them. The testing of hydrogen sulphide were successful, it showed that the gas had lethal concentration at 300 yards from the point of release. Hydrogen sulphide was short lived, it was discovered that it’s was too dangerously flammable, and it corrodes the cylinders that it’s stored in, it was also to light to stay near the ground after release, and possessed a distinctive smell at very low concentration which is an early warning to the enemy.

The French were the first to start experimenting on chemical agents in 1912. They first used it on their people as riot control to capture criminals that who had robbed a bank. They used 26 millimeter grenades filled with chemical agents into the center of the group criminals they were attempting to apprehend. It was not said if it was effective but continued to look into using it for other means. However, the Germans at this time had not been interested in producing any kinds of chemical weapons.
In the late 1800’s it was discovered that papa-amino-phenol, could reduce fever, but the drug was too toxic to use. A less toxic extract called phenacetin was later found to be just as effective but also had pain-relieving properties. In 1949, it was learned that phenacetin was metabolized into an active but also less toxic drug, acetaminophen. Since then, acetaminophen has been sold under many over the counter brand names, most popular being Tylenol.
LSD stands for Iysergic acid diethylamide. LSD is a hallucinate know to be the most powerful drug of this kind. LSD is commonly known as acid. This drug changes a person’s mental state by distorting the perception of reality to the point where at high doses hallucination occurs. Acid is derived from a fungus that grows on rye and other grains. It is semi-synthetic. It’s manufactured chemically in illicit laboratories, except for a small percent, which is produced legally for research.
Bleaches are used as household chemicals to whiten clothes, remove stains and to be used as disinfectants, often by oxidation (Mittal, 2007). Numerous types of bleach contain strong bactericidal properties, and are used for disinfecting and sterilizing, thus why chlorine-based bleaches are popularly used in swimming pool sanitation to control bacteria, viruses and algae and in any institution where sterile conditions are needed (Reader's Digest). Chlorine is the basis for commonly used bleaches; for example, the solution of sodium hypochlorite. The concentration of chlorine-based bleaches are often expressed as percent active chlorine, where one gram of a 100 percent active chlorine bleach has the same bleaching power as one gram of chlorine. These bleaches can react with other common household chemicals like vinegar or ammonia to produce toxic gases (Bleach, 2014).
Submerged in water, it was the fourth of July on Grayling Island, the Senator's rented Toyota whistling tunes of the Beatles, topics of debate: the Vietnam War, Dukakis, skidded off the road. Lizzie, "Kelly" they are not the same, she can't die like this, no not now. She was someone's little girl, not a bad girl, she wasn't a bad girl, she told her mother she wasn't don't mention G____, was she ready? Her white anklet socks flew into the air as massive male hands, Grandpa's hands, swept her off her feet saving her from the black waters rushing in, they didn't have to know, they wouldn't have to tell Grandma, Grandpa was spared, he died several years before. Kelly wrote a paper on the senator, her senior thesis, she grabbed on to his leg, his shoe, "oh how Buffy would laugh, his shoe, his empty shoe?", she wasn't pretty, but it was her time, she didn't believe in the stars, but today she listened to her horoscope: go for what you really want, or something to that effect, black water rushed in and she died; she's here, she's here, SHE'S HERE!, "caution: ultra-violet rays, saltwater swimming, and overheated blow dryers are serious dangers to Beautiful Hair," Pluto was not originally a man but a woman, black water rushed in and she died.
- The amount of times the mixture was stirred. We stirred the mixture until the Ammonium Nitrate was dissolved, so the amount of times we stirred after each teaspoon was different.
Hydrochloric acid is a strong and corrosive acid that is often used as a reagent in laboratories.
Haber, however, pushed for Chlorine gas to be used in combat. The gas was used with 5,730 cylinders which were set up on a road just north of Ypres in Belgium. At first, this looked unsuccessful, but soon the wind took the gas and it spread causing many effects of the other troops. Haber is now known as “The Father of Chemical Warfare”, (Riddle). However, as the war progressed, the soldiers were noticing the chlorine gas quicker and avoiding the effects by putting clothes over their noses and mouths. So, because of the chlorine gas failure, a new chemical weapon replaced the Chlorine gas: Phosgene gas. French scientists were one of the firsts to use Phosgene Gas. Phosgene gas is Carbonyl dichloride, which is a compound composed of the elements Carbon, Oxygen, and Chlorine. This gas affected the lungs and caused sneezing, coughing and vomiting. This gas was odorless and didn’t produce any cloud. It was a lot more dangerous than Chlorine Gas, since it was undetectable. Phosgene gas accounted for 80-85% of chemical weapon deaths during World War I, (Riddle). Chemical weaponry developed slowly, yet effectively throughout the course of World War I. Along with chemical weapons, small grenades, flamethrowers, and little household weapons played their part in the first ever world war. The
With regards to the usage, AgCl is used extensively for various routines. The low solubility property of AgCl serves a use in the making of ceramic glazes and other various artworks. As a medication, silver chloride has been used as an antidote for mercury poisoning, as it completely eliminates the mercury once it the bloodstream. As a medical device, silver chloride comes in the form of bandages and in other wound healing products. In the photographic industry, AgCl is used produce photographic paper, as silver chloride reacts with photons and produces latent images. It also used in the production of photochromic lenses, as it can be converted into an Ag metal during ultraviolet encounter. Silver chloride is utilized in the long-term preservation of drinking water in water tanks. These are various utilizations of the compound. There are many other methods in using AgCl, however examples stated above are some of the common, everyday usage of silver chloride.
