  • Polyvinyl Chloride Plastisols

    In this study, the changes in the rheological curves of polyvinyl chloride (PVC) plastisols with increasing storage time and the factors affecting the changes were studied,. The results show that with increasing storage time, all the "viscosity–temperature" and "viscosity–time" rheological curves of PVC plastisols exhibit non-normal distribution change trends, i.e., the viscosity first decreases, and then changes from slow increasing to rapid increasing, forming a shoulder peak, reaches to the maximum value and gradually decreases. With increasing storage time, the viscosity of PVC plastisol changes significantly in each stage, exhibiting an overall increasing trend; however, the corresponding transition temperature and time of PVC plastisol did not change. Keywords: Poly vinyl chloride; plastisol; rheology; storage time; viscosity Polyvinyl) chloride (PVC) plastisol refers to the suspension dispersion system formed through stirring and dispersing PVC paste…

  • Flame Test Lab Report Essay

    In this experiment, two cations in an unknown solution were found using qualitative analysis. For Part A, the solution was to contain either silver or lead, while in Part B, the solution that was set on the side form Part A was identified to contain either calcium or barium. Part C explored a different method through the use of cation flame tests to observe colored flames from six metal chloride solutions. In Part A, the initial step was to add HCl to the unknown sample. This was necessary…

  • Osmosis And Potato Cells Lab Report

    Other groups were assigned with glucose and sucrose. Diluting 1 M of sodium chloride with water made six solutions. The six solutions ranging from 0M to 1M were prepared. These 6 solutions composed of 50 mL of solutions with different concentration of NaCl. The uses of concentrations of NaCl were 0M, 0.2M, 0.4M, 0.6M, 0.8M, and 1M. Then 6 equally sized and shaped cylinders of potato were obtained and weighed initially. Then these 6 potatoes were put inside of the sodium chloride solutions. After…

  • Biodegradation By Fenton Reaction Lab Report

    Phenols Degradation by Fenton Reaction in the Presence of Chlorides and Sulfates Siedlecka et al. (2005) also studied a series of phenol compounds present in wastewater. These compounds, as mentioned above, are widely used therefore are commonly found in wastewater derived from different industries such as petrochemical, food or resin manufactured. Since common biological treatment for these kinds of compounds is not feasible, is important to develop new technologies to treat these…

  • Copper Chloride Lab Report

    Introduction and Historic Background Copper (II) chloride is often times called cupric chloride. The molecular formula is CuCl2. There are two forms of copper (II) chloride. One form is the anhydrous form, which is when the copper (II) chloride is a yellowish-brown powder. It has a boiling point around 993 degrees Celsius and a melting point near 630 degrees Celsius. If copper II chloride is in its dihydrate form, it is a green-crystalline solid. The formula weight of the dihydrate form is…

  • Baccl2 Test Lab Report

    If the substance clumps at the bottom, continue to stir until the mixture is dissolved completely. Take a clean volumetric pipette and set up five test tubes. Using the pipette, portion out 0.1 ml of the unknown solution and place it into each test tube. This will evenly divide the solutions for testing. pH Test Fig. 1 The purpose of the ph test is to determine whether the solution is acidic or basic. Next, taking a ph strip, dip the end of the strip into the solution to gauge the ph.…

  • Polyvinyl Chloride: A Case Study

    Do you know what PVC pipe is made out of? Polyvinyl Chloride. A colorless and odorless plastic that is often connected to reproductive and developmental health issues. The same material your faucet water runs through. Despite this, it stands to be the world’s third most produced synthetic plastic. This material does not stand alone in being one of the least sustainable and most toxic chemicals. The International Living Future Institute has produced a ‘Red List’ that mentions 21 more materials…

  • Ferric Chloride Test Lab Report

    Introduction The ferric chloride test is used to determine the presence of phenols in a given sample or compound (for instance natural phenols in a plant extract). Enols, hydroxamic acids, oximes, and sulfinic acids give positive results as well. The ferric chloride test can be used to detect metabolites in urine in case of inborn error of metabolism such as phenylketonuria. In addition,the Ferric Chloride test can be used to detect salicylates in urine after an aspirin overdose.1 Background…
