If the total alkalinity is normal, pH increaser should be added according to the instructions on the containerbefore trying to increase the pH. pH+pOH=14 pH=-log⁡(H+) pOH=-log⁡(OH-) pH=14-pOH pOH=14-pH The term “free chlorine” refers to hypochlorous acid ( ) which exists

Pool Operations Pool Operator, Records and Plans The pool operator has appropriate training for maintaining and operating the pool. In addition, the operator was also the only caretaker of the pool and was knowledgeable and active with the pool safety plan and pool records. To illustrate this, the operator knew where the safety equipment were located in the pool area; how to balance and maintain the pool water; and performed the regular maintenance and cleaning of the pool. Also, the Fraser Health

Chlorine is a chemical element with symbol Cl and atomic number 17. Chlorine is a pale yellow, green gas under standard conditions. Chlorine atoms have an electron configuration of (2, 8, 7) and 7 outermost shell electrons. Chlorine is in group 17 and period 3 of the periodic table. Chlorine commonly forms the anion Cl- by receiving an electron, reaching a stable electron configuration. Chlorine is a halogen. Bromine is a chemical element with symbol

gases, chlorine, phosgene and mustard. Tear gas agents are known to cause crying, coughing and respiratory difficulties to those affected. In WWI, tear gas was first used in 1914 by France against the Germans. There were no documented fatalities with this chemical weapon. Chlorine was first used as a chemical weapon in WWI in 1915. It was used by the Germans against the British in Yrpes. In its first use, chlorine caused more than 1,100 fatalities. Later on in the war, the effects of chlorine were

stumbling / And flound’ring like a man in fire or lime…” (11-12). These lines described an unfortunate soldier who did not respond swiftly enough to the chemical attack and knowingly panicked as he succumbed to a lethal dose of chlorine gas. When this soldier inhaled toxic chlorine gas, his lungs literally filled up with bodily fluid because his airway tissue was burned (Fitzgerald 613). Owen used the word “lime” in reference to “a caustic highly infusible solid that consists of calcium oxide often together

discovery came the introduction of UV radiation lamps, which emit similar UV rays to the sun to disinfect the water. Chlorination systems had come into use a few years later during the 1900’s as scientists had discovered the disinfection properties of chlorine. Both methods have benefits and weaknesses, however chlorination is more suitable due to its low cost of production and decreased risk of bacterial products in metropolitan areas. The treatment process involves the removal of contaminants through

battle fought in World War I because of the chemical warfare and Germany’s use of advanced technology. After a torturous month of fighting the German army, however, the Canadian soldiers emerged victorious. The Germans used chemical warfare, namely chlorine gas, against the Canadian soldiers. Chemical weapons were prohibited by international treaties before World War I. On April 22, the Germans released more than 160 tons of the gas from thousands of canisters arranged along German lines. The soldiers

A traditional pool uses chlorine tablets, sticks, or granules. “The active ingredient in 3” tablets, 1” tablets and sticks is called “Trichlor” (or Trichloro-S-Triazinetrione), and the active ingredient in granular

liquid at room temperature. In it has a brownish-red color with a bleach-like odor and it dissolve in water. An found in bromine is a naturally in the earth’s crust and in seawater in various chemical form. Can also be found as an alternative to chlorine in swimming pool. Then some product containing bromine are used in agriculture and sanitation as an fire retardants. Bromine was discovered in 1826 and it was discovered by Antoine-Jerome Balard in Montpellier. The origin of the name came from

Analysis and Electrolysis. Desalination of water by chlorine is considered one of the applications of analytical chemistry.
