Properties of Gases Essay Example for Free

Properties of Gases risePurposeThe purpose of this experiment is to examine assorted properties of gasolinees in order to be able to rate them in a laboratory setting. I will be using Hydrochloric acid, mossy zinc, Bromothymol blue, limewater, Manganese, and Alka soda pop, to ravel different properties of gases organiseed by chemical chemical reactions. In order to extract the gas I will exercise several household products such as vinegar, baking sodium carbonate, water, and hydrogen peroxide in order to become the gases to be screened.MaterialsStudent Provided1 Match1 Toothpicks (or wooden treats)1 Pie tin or ex sortable1 Marker pen1 Household white vinegar1 3% atomic number 1 peroxide (H2O2)1 Measuring spoons1 Drinking straw1 Tissue paper1 Baking soda (sodium bicarbonate)From LabPaq 1 Goggles-Safety1 Test Tube (5), 13 x 100 mm in Bubble Bag1 Well-Plate-24Auxiliary SuppliesBagAuxiliarySupplies Bag-CK11 Gas manufacture copper/plastic tubing in 00Stopper1 Pipet, Empty Short bag1 Rubber secure, 00, 1 hole, Pipet tip w/plasticGas delivery tubing try Bag Properties ofGases 2 Alka Seltzer (1/4 tablet) in Bag 2 x 31 Bromothymol Blue, 0. 04% 4 mL in Pipet1 Hydrochloric Acid, 2 M 20 mL in DropperBottle1 Limewater (Calcium Hydroxide, Saturated) 6mL in Pipet1 Manganese alloy Pieces 4-6 Pieces in Bag 2x 33 Pipet Bulbs, Wide-Neck with 1/4 Stem1 Zinc, Mossy 4-6 Pieces in Bag 2 x 3Procedure1) Hydrogena) I fit(p) a small amount of ZN( mossy zinc) in the test tube containing HCL b) I then(prenominal) capped the test tube with the small cap that allowed gas release from the top and pose it in one of the 24 healthy plates. I wedged the test tune in with a snap of toilet paper. c) I then change the large stem pipet with water and placed it atop the rubber stopper. d) I placed the well plate in a pie tin to prevent the inundation from getting everywhere. e) After the water was replaced entirely with hydrogen I remote the wide mouthed pipet and p laced my finger oer the opening to prevent any gas from escaping. f) I lit a fit out and while holding the pipet about 1cm a centering from the flame blew the gas onto the flame, and enter my observations in the table. g) With a marker I marked the wide-neck pipet on the outside into three parts h) I filled the bulb with water and set it on the test tube as before. i) Once the bulb was 2/3 full of gas I removed it and placed it aside, still inverted, for later use j) I then disassembled and rinsed the tools and threw away the ZN.2) group OA) I placed a few sets of Mn (Manganese) into the second test tube. B) I filled the test tube to within 1cm of the top with hydrogen peroxide. Afterwards I placed the rubber stopper on the test tube and the test tube in the well plate. . C) I then filled an some other wide-neck pipet completely withwater and placed it on the top of the stopper in the test tube. D) After the water was displaced I removed the pipet and placed my finger over the opening to prevent any gas from leaking. E) I lit a tick and extinguished it. time the match was still glowing I placed it inside the pipet and recorded the reaction.3) Hydrogen and Oxygen MixtureA) I took the pipet from part 1 that is partially filled with hydrogen and placed it on the generation test tube from part 2. B) I let the bulb fill until the water was completely displaced. The mixture was about 2/3 hydrogen and 1/3 oxygen C) I removed the bulb and placed my finger over the open end to prevent any gas from escaping D) I lit a match, held the pipet horizontally about 1cm away from the flame and squeezed the gas onto the flame. E) I recorded my observations in the table.F) I disassembled the test tube washed the contents bundle the drain and rinsed the tools.4) Carbon DioxideA) set out Ia) I placed approximately .5 ml of limewater in one well of the 24 well plate. b) I placed a teaspoon of baking soda in the generation test tube. c) I filled a pipet halfway with vinegar and added it to the baking soda. Immediately after the cardinal stop reacting I placed the rubber stopper with the copper and plastic gas delivery tube on the top of the test tube. d) I placed the open end of the tube into the well with limewater and recorded the reaction.B) theatrical role IIa) I placed approximately .5ml of Bromothymol blue in one of the wells. b) I thoroughly rinsed the gas generation test tube with water and set up another test with baking soda and vinegar as in part 1. c) After targetting the stopper in place I inserted the open tube into the Bromothymol blue. d) I removed the stopper from the generation tube.e) I lit a match and inserted the flame into the upper part of the test tube.f) I recorded my observations.C) Part IIIa) I poured the chemicals down the sink and flushed with water.b) I put approximately .5 ml of limewater into another well.c) I crumbled the small piece of Alka Seltzer into a test tubed) I added one pipet full of water to the test tube and immediately inserted the stopper with the gas delivery tube.e) I placed the open end of the tube into the limewater well.f) I washed the test tube and well thoroughly with water.D) Part IVa) I put approximately .5 ml of limewater into a test tube.b) I inserted a straw and blew for a few seconds.c) I recorded my observationsd) I washed the tools and flushed the limewater down the sink.ResultsGasFlame reactionGlowing splintLimewater reactionBromothymol blue reactionHydrogenLoud drop dead, flame went outn/an/an/aoxygenn/aLight up quickly disperse and glowed for around 10 seconds n/an/aHydrogen oxygenPopping sound and flame went outn/an/an/aCarbon Dioxiden/an/aChanged the color of the limewater from clear to nearly milky, bubbled rapidly.

First we do this because maximizing the pressure in the tube will maximize gasses. Secondly because this causes there to be a shorter keep for the gases to traveledB) What happens to the zinc in the hydrogen generation experiment? The mossy zinc causes a reaction with the HCL to form hydrogen gas.C) What happens in the oxygen generation experiment?The manganese reacts with the hydrogen peroxide to form oxygen.D) Write a balanced equation for the reaction between O2 and H2. 2H2 +O22H2OE) What is the function/purpose of the Bromothymol blue in the carbonic acid gas experiment? The Bromothymol blue in the CO2 experiment is used to indicate how much CO2 is in the solution. It indicates this with a color change.F) Bromothymol blue is blue in the presence of basic solutions and yellow in the presence of acidic solutions. If your solution is a murky green, whatmight you assume about the solut ion I would assume the solution was neutral.ConclusionIn conclusion, I learned that properties of gases vary vastly in their reactions with flame, and other substances. I also learned how to create such gases in a controlled environment for future experimentation. The frame of these reactions put into perspective how dangerous gases can be and how their proper storage and transportation is a merry essential in our daily lives. Seeing the different reactions will make me more cautious of the way I materials.
