Processes in Producing a Chemical Reaction and Hazards

Processes in Producing a Chemical Reaction and HazardsElephant Toothpaste intent/aimUnderstand the processes involved in producing a chemical replyIdentify hazards involved with victimisation particular chemicalsDemonstrate an understanding of interpersonal chemistry terms such as catalyst, oxidation, and exothermic (Harper Nickels, 2008).Background schoolingThe elephant toothpaste experiment is an experiment that produces great kernel of steaming foam (Helmenstine, 2014). Its great step of foam is what makes it disembodied spirit handle a toothpaste an elephant would use. The experiment makes use of enthalpy hydrogen hydrogen hydrogen peroxide (H2O2) solution. Hydrogen peroxide is a germiadral agent composed of irrigate and oxygen. It kills disease organisms, like ozone does, using oxidation. It kills microorganisms by oxidizing them which can be described as a Controlled burning process (Hinrichs, 1986).When hydrogen peroxide reacts with organic material, it happy chance s down into oxygen and water. It can be used in varies ways example, disinfection, mouthwash, hair lightening and contact lenses. In our bodies hydrogen peroxide is produced to press out infections, which must present for our immune systems to function correctly and healthy (Helmenstine, 2014). White blood cells are cognise as leukocytes, a sub-class of these cells Neutrophils produces hydrogen peroxide as the first defence against toxins, parasites, bacteria, viruses and barms (Helmenstine, 2014).Hydrogen peroxide is or so used in toothpastes and as a cure for toothaches. In this experiment we also use yeast or saturated potassium iodide solution as a catalyst to make the peroxide soupcon release the oxygen faster (Harper Nickels, 2008). Yeast is a fungi which converts the catalase hydrogen peroxide into harmless water and oxygen (Spangler, 2013). The overall equation for this reaction is2 H2O2 (aq) 2 H2O (l) + O2 (g)The decomposition of the hydrogen peroxide into water and oxygen is catalysed by the iodine ion or dry yeast. It also releases a small amount of the heat so the reaction is exothermic. (Helmenstine, 2014)H2O2 (aq) + OI (aq) I (aq) + H2O (l) + O2 (g)The dishwashing detergent used captures oxygen as bubbles. Food colouring adds colour to the foam which can be optional.Chemicals and MaterialsYou will need20mL Hydrogen peroxide (30%)5mL Sodium iodide solution 2MDishwashing liquidFood colouringRubber gloves for clean up (Harper Nickels, 2008).Labware and frame-upA funnelDropperBeaker500 mL Graduated cylinderSafety goggles tensile bottleful (2l Cold drink bottle)Glass robSpatulaSafetyHazardsThe bottle will become truly hot. Allow the bottle to cool forwards touching it directly.Hydrogen peroxide is a very ardent oxidizing agent and whitethorn cause severe strip burn. interpose hydrogen peroxide in a cool, dark landing field apart from reducing agent and organic materials.Do not lean over the bottle when solutions are mixed it is an exo thermic reaction.Experiment should not be done near an uncivil flame.The solution can be washed down the drain with excess water (Carolina.com., 2014).Experimental numberPut on your goggles and gloves.Have a couple of students feel the side of the graduated cylinder. measure out 60ml of hydrogen peroxide from your source bottle into the beaker. Pour the entire 60ml into the bottom of your container.Place 10g of potassium iodide in the plastic portion cup. Add 10ml of water and 3ml of liquid detergent. Stir all the chemicals together using a wooden stick.Open the bottle of food colouring mixed half and half with glycerine or corn syrup and exactly 2ml of the dye. Dribble it down one side of the container that you are using.Add the confection of soap, water and potassium iodide to the hydrogen peroxide in the container. The potassium iodide will separate into potassium and iodide ions. at a time the experiment is complete ask a couple of students to come up and carefully touch the sides of the bottle and describe the temperature for all the other students in the science laboratoryoratory (Meerman, 2009).Outcome of experimentThe experiment produces a bouffant amount of foam as a result of the dishwashing detergent that was added. The foam shoots out of the container like toothpaste would if you squeezed the container. The foam produced is safe to play around with as they yet contain soap and oxygen from the hydrogen peroxide. We will also observe the catalytic reaction rate by the combining of yeast, hydrogen peroxide and dish washing liquid detergent (Spangler, 2013).Source of experimentSteve Spangler Science. (2008).

May cause skin irritation, redness, swelling and formation of blisters.Ingestion Causes Nausea, vomiting and diarrhoea, gastrointestinal tract burns. May cause difficulties in swallowing, hold up distension, possible cerebral swelling and death. Ingestion might also result in irritation of the esophagus, shed blood of the stomach and ulcer formation.Inhaling Can cause burns in the respiratory tract causing emaciated tissue, insomnia, nervous tremors with numb extremities, chemical pneumonia unconsciousness and death. At high concentration respiratory effects may cause acute lung damage and delayed pulmonary oedema.Chronic Can cause dermatitis due to extensive or repeated skin contact. Mutagenic effects and corneal damage if repeatedly contacted.First concern MeasuresEyesGet medical aid immediately. Do not rub eyes or make eyes closed. Extensive irri gation with water is required immediately.SkinGet medical aid immediately. Flush skin with plently of water for at least 15 minutes while removing contaminated clothing. Wash clothing before reuse.IngestionDo not induce vomiting. Give 2-4 cups of milk or water, if unconscious dont delve anything, get medical aid immediately. Wash mouth out with water. Vomiting may occur, give water to further dilute the chemical.InhalationGet medical aid immediately. Move person to clear air immediately. If breathing is difficult, give oxygen. Do not perform mouth to mouth. You can use a bag and a mask for artificial respiration if breathing ceases.Fire MeasureUse only water, do not use dry chemicals or pour water into containers. Contact professional send packing fighters immediately. Cool containers with flooding quantities if water until well after fire is out. For large fires, flood fire area with large quantities of water while knocking down vapours with water fog.HandlingWash transfer thor oughly after handling. Wash contaminated clothes before reuse. Use only in a well ventilated area. Do not get in eyes, skin or on clothing. Store protected from light. Unused chemical must not be returned to the container.StorageKeep away from heat, sparks and flame. Do not store near combustible materials. Keep containers closed when not in use. Store away from light. Store only in light resistant containers fitted with a safety vent.Questions and AnswersWhat type of reaction is this? rotting (1)What happen to the reaction when the iodine is drop into the hydrogen peroxide?There is a large amount of heat released and the hydrogen peroxide is decomposes in to water and oxygen.
