Chlorine

4. Discussion Based on the results, the hypothesis was not correct. It was hypothesised that the control sample would retain the most chlorine, and light would retain the least, with stabiliser and cover between them. The results gathered were very different, showing cover as the best, retaining 70.2% of the original OCl-, and stabiliser as the worst with only 50.3% of OCl- remaining. The control and light samples were situated between them, with an OCl- retention of 58.6% and 56.1% respectively

simple weapons to chemical attacks. The threat of chlorine attacks has to be considered with the ever growing use of it in Iraq and Syria. This discussion will look at the history of chlorine as a weapon. Then review current uses of chlorine as a weapon by Islamic extremist. Afterwards, theoretically look at how a chlorine weapon should be used in the United States, specifically Las Vegas. Then finish with how to prevent that attack. Chlorines history was never intended to be used as a weapon

2.1. Properties of Chlorine 2.1.1. General Chlorine has a characteristic penetrating and irritating odor. The gas is greenish yellow in color and the liquid is clear amber. The data on physical properties of chlorine as determined by different investigators show some variations. Atomic and Molecular Properties Atomic Symbol - Cl Atomic Weight - 35.453 Atomic Number - 17 Molecular Weight of Cl2 - 70.906 Physical properties Physical Properties Property Definition Conditions Value Boiling Point (Liquefying

Chlorine is a dangerous solution when not properly used correctly. It has negative and a few positive effects. Also, developing a limited amount of time around it can help prevent some effects caused by think compound. Chlorine can develop many effects on physical features, someone who is not in use of a chlorine pool, and the health risks of an individual. Unlike pure water, chlorine added into a swimming pool not only has good effects but bad effects on physical features too. A positive effects

net dipole the shape of the water is bent. Chlorine is naturally found as a gas which can be manipulated to different forms in Earths’ biosphere. In its natural form chlorine is a poisonous gas, which can has the potential to kill people if over 600ppm of chlorine is consumed. When chlorine is compressed and cooled to -100.98oCit forms into a transparent liquid. Chlorines gas is green and explosive, but when in a liquid form it becomes stable. Chlorine is a common yet fundamental chemicals used

Chlorine is the 17th element on the periodic table, and at -34 degrees Celsius and above it becomes a yellow gas that is fatal to humans. The use of chlorine gas as a poison on the battlefield came quickly after the start of World War One. It’s has been heavily influenced by politics, and sometime politics fails to limit harmful uses. To this day weapons grade chlorine gas is stockpiled and occasionally used despite multiple United Nations (UN) restrictions and international agreements. A political

Chlorine is the main chemical used in pools to sterilise pools by destroying harmful organisms such as bacteria and algae. A reaction takes place with water to produce hypochlorous acid, HOCl, and chloride ions Cl-. Cl2 (aq) + 2H2 O HOCl(aq) + Cl-(aq) + H2O Equation 1 The hypochlorous acid dissociates almost immediately into hydrogen and hypochlorite ions (OCl-). 2H2O + HOCl(aq) H3O +(aq) + OCl-(aq) (pKA = 7.54) Equation 2 The presence of H3O+ directly affects the pH reading. This reaction forms

find out how much chlorine remains in a pool each day after chlorination. I am interested to see how much residual chlorine is left and the range in which there appears skin irritation and red eyes because I have experienced the red eyes and itchy skin due to over chlorination. Chlorine is used in pools in either a gaseous or as sodium or calcium hypochlorite. The chlorine is added to water to help prevent people from getting sick from disease-producing microorganisms. The chlorine that is added and

Despite the significant benefits of pool chlorines in their capacity to kill hazardous bacteria, it is evident that some of the side effects can be disadvantageous. The general smell of chlorine can be overwhelmingly unpleasant, and the agent can irritate the skin and eyes. It is also has the capability to bleach some fabrics, potentially damaging clothing. Most significantly, excessive air pockets of chlorine gas that surround pools can be hazardous for peoples’ health and possibly even be carcinogenic

Chlorine kills pathogens such as bacteria and viruses by breaking the chemical bonds in their molecules. When chlorine is added to water, chloric acids forms: Cl2+H2O = HOCl + H+ + Cl-. Depending on the pH value, chloric acid partly expires to hypochlorite ions: HOCl = OCl- + H+. Hypochlorous acid (HOCl) and hypochlorite ions (OCl-) will form free chlorine when bound together, and they are primary disinfectants throughout the process. However, the chlorine dosage has to be high enough to reach
