dependant on whether or not a precipitant formed or there was a color change. Both of these indicate a reaction has taken place. The alkaline earth metals are barium, beryllium, calcium, magnesium, radium, and strontium. And the halogens are fluorine, chlorine, bromine, iodine, and astatine. Experimental Procedure: This experiment is broken up into two parts. The first part involves Alkaline Earth Elements. First one drop of 1 M Na2CO3 is added to one drop of each alkaline earth solutions, 1 M

chemical warfare that were used that could have caused the symptoms which were described by Owen. The first of these gasses is chlorine. In the poem, Owen describes the color and effect of the gas as “Dim through the misty panes and thick green light, as under a green sea I saw him drowning” (486). With this description we can speculate that the gas used is chlorine. Chlorine gas does

Chemical Warfare in the First World War The First World War, while engulfing Europe with four years of death and destruction, also served as something of a testing ground, allowing nations to test and deploy the newest and most high tech weapons in their arsenals. It is from these experiences, on the bitter, mud drenched fields of Flanders, Eastern Europe, and elsewhere, that many technologies that shape the modern battlefield today, such as the air plane or the tank, were first put to use on a

Introduction • Chlorine is widely used industrial chemical agent with corrosive properties and a potential weapon of mass destruction. • At standard temperature and pressure exists as Greenish-yellow color gas with suffocating pungent odor. Under high pressure or low temperature, it turns to clear, amber-colored liquid.1 • Chlorine is heavier than air, and therefore it will remain near the ground in areas with little air movement.1 • It is used in water treatment, household cleaning products

RADICAL HALOGENATION AND GAS CHROMATOGRAPHY Abstract In radical halogenations lab 1-chlorobutane and 5% sodium hypochlorite solution was mixed in a vial and put through tests to give a product that can then be analyzed using gas chromatography. This experiment was performed to show how a radical hydrogenation reaction works with alkanes. Four isomers were attained and then relative reactivity rate was calculated. 1,1-dichlorobutane had 2.5% per Hydrogen; 1,2-dichlorobutane had 10%; 1,3-dichlorobutane

Introduction: Today, swimming is very much an enjoyable activity as a form of recreation, exercise, or physical therapy, as well as a disciplined competitive sport. Early Swimming: In the olden days, swimming was basically an exercise, seen as a life skill, and therefore, people would commence controlled coaching. However, swimming races took place in Japan as early because the 1st century BC, and swimming was a mandatory part of the college curriculum in Imperial Japan (Britannica, 2005).Also,

temporary incapacitation or sensory irritation through its chemical action” (Organisation for the Prohibition of Chemical Weapons, n.d.). Chemical weapons have been around for a long time since ancient times, in fact some chemical weapons such as chlorine were frequently used during World War I (War of nerves, 2006) (Pitschmann, 2014). Over the years with the increase of industrialization and the advancements in technology chemical weapons have become easier to make, since the materials needed to

water treatment today (i) free chlorine, (ii) combined chlorine (chloramine), (iii) ozone, (iv) chlorine dioxide, and (v) UV light. The first four disinfectants are chemical oxidants whereas UV light involves the use of electromagnetic radiation. Of the five, by far the most commonly used disinfectants, in both plants and distribution systems, are chlorine and chloramines. Chlorine dioxide, ozone and UV are also used on a limited basis to meet disinfection goals. Chlorine or chloramines are the most

because of his idea that chlorine had the properties to disinfect water for drinking. It was thought at the time, that if chlorine is poisonous when in a gaseous state, then what’s to say that it’s not poisonous when it’s added to water (creating calcium hydrochloride), which it was (reference 1).Leal spent years of his life observing the effects were when very small amounts of chloride of lime was added to bacteria filled water. He observed in more cases than not that the chlorine of lime in the water

effect of bleach on human health? Some background information about bleach before we begin is that it is a pale yellow liquid that has a chlorine odor (Sodium 2016). The manufacturers generally supply bleach as a dilute aqueous solution because it is extremely reactive and unstable.  Bleach will eventually decompose into a variety of by-products, such as oxygen, chlorine gas, and salt (Schueller 2014). To prevent this decomposition from occurring too rapidly, bleach should be stored away from light or
