Chemical Thinking P1 In-Lab Worksheet v4.0 | 1Project 1 In-Lab WorksheetYour TA’s name: Xien Chen Your name: Sarah JangLab section: 4F Your email: [email protected] ____ /5 p + WS ____ /20 p = GRADE ____ /25 p Your Lab Partner: Kirsten ArrizAll work must be well-written and organized. If your penmanship is poor, you must type all responses. If you needto organize your thoughts, please use a separate sheet of paper. A major objective of this lab course is to developskills in scientific communication. Just having an “answer” is not good enough – you must communicate clearlyand succinctly and use terms and concepts correctly.1. Task 2 Validating the Process (12 p) With your lab partner, decide which Task 1 process diagram or flowcharthas the most promise. Then devise experiments to confirm or otherwise validate this process/flowchart. Theexperimental scale must remain on the milli-scale level (1 – 10 mL liquid, 0.25 g of plastic or less). Otherwise theexperimental design is largely up to you. In the tables provided below clearly indicate what you are testing for, howyou are testing for it, what the results are, and your analysis/conclusion from the results . Use your lab notebook torecord observations and other details that may prove important in building your final flowchart. You must conductenough experimental work to support your final flowchart/process – in this task you are providing “proof ofconcept” for your separation process based on density as a differentiating characteristic.Table P1: Summary of Experimental Work for the Development of a Density-based SeparationExperiment/Test 1Aspect of the flowchart/diagram being tested. (What are you testing?)The density of PETE, HDPE, PP, and PS in NaCl. If they will sink or float or be buoyant.Brief description of the experimental approach. (How are you testing it?)By using 10 mL of NaCl, we will put in around .20 g of PETE, HDPE, PP, and PS. Using the forceps to movethem around, we determine which plastics will sink, float, or both. Results obtained from the experiment. (What are the results?).20g PETE= Sunk.20g PP= Floated.20g PS= Floated.20g HDPE= FloatedAnalysis. (What can you conclude from the results?)The density of PETE (1.3-1.4 g/mL) is higher than NaCl. The other plastics had a density lower than NaCl.PP is 0.85-0.90 g/mL, HDPE is 0.95-0.97 g/mL, and PS is 1.02-1.04 g/mL.P1 In-Lab v4.0 MY © 1-19-17 Chem Think Technical Press CBC UofAThis study source was downloaded by 100000851493797 from CourseHero.com on 10-31-2022 00:01:52 GMT -05:00https://www.coursehero.com/file/23589990/P1-In-Lab/Chemical Thinking P1 In-Lab Worksheet v4.0 | 2Table P1: Experiment/Test 2Aspect of the flowchart/diagram being tested. (What are you testing?)The density of PS, HDPE, and PP in water. Will it sink or float?Brief description of the experimental approach. (How are you testing it?)By using 10 mL of water, we will put in around .20 g of PETE, HDPE, PP, and PS. Using the forceps to movethem around, we determine which plastics will sink, float, or both.Results obtained from the experiment. (What are the results?).20g PS= neutrally buoyant.20g HDPE= Floated.20g PP= FloatedAnalysis. (What can you conclude from the results?)The density of water is 0.998 g/mL and the plastic, PS, is 1.02-1.04 g/mL which are very close in densityso PS was neutrally buoyant. HDPE and PP had a lower density.Table P1: Experiment/Test 3Aspect of the flowchart/diagram being tested. (What are you testing?)The density of HDPE and PP in 5 mL of ethanol and 5 mL of water mixed together. Will it sink or float?Brief description of the experimental approach. (How are you testing it?)By using the mixed solution of 5 mL of water and 5mL of ethanol, add in .20g of HDPE and PP. Using theforceps, mix the plastics around to get better results. Results obtained from the experiment. (What are the results?).20g HDPE= sunk.20g of PP=buoyantAnalysis. (What can you conclude from the results?)The density of the mixed solution is around .8 g/mL and PP is 0.85-0.90g/mL so it was neutrally buoyantbecause they are both very close is density. HDPE has a heavier density than the mixed solution so it sunk.P1 In-Lab v4.0 MY © 1-19-17 Chem Think Technical Press CBC UofAThis study source was downloaded by 100000851493797 from CourseHero.com on 10-31-2022 00:01:52 GMT -05:00https://www.coursehero.com/file/23589990/P1-In-Lab/Chemical Thinking P1 In-Lab Worksheet v4.0 | 3Table P1: Experiment/Test 4Aspect of the flowchart/diagram being tested.

Task 2 Final Flowchart (4 p) Present your final process diagram or flowchart for the efficient andenvironmentally sound density-based separation of PETE, PP, PS and HDPE using only the available liquids. Theflowchart must be titled, well organized and properly labeled. If you are not familiar with building a flowchartusing your computer, then draw the flowchart by hand being certain that everything is legible and neat.P1 In-Lab v4.0 MY © 1-19-17 Chem Think Technical Press CBC UofAPETE, PP, HDPE, PSSeparation of PlasticsPETEHDPE,PPPP,HDPE,PSPSSodium Chloride1.19 g/mLSinkFloatNeutrally BuoyantWater 0.998 g/mLFloatHDPESink5 mL water and 5 mLethanol .8 g/mLNeutrally BuoyantPPThis study source was downloaded by 100000851493797 from CourseHero.com on 10-31-2022 00:01:52 GMT -05:00https://www.coursehero.com/file/23589990/P1-In-Lab/Chemical Thinking P1 In-Lab Worksheet v4.0 | 53.
