Chemical Thinking Project 5 Report | PROJECT 5 REPORT All sections must have a line spacing of 1.5 to give room for TA feedback (the document is set to this spacing) Defining the Problem/Question For the Project 5 lab, pillows were created using a combination of four different materials: spun bounded polyester, micro punctured polypropylene, spun polyester and polyethylene liner. The purpose was to see what combination would be best to absorb heavy metal ions in A 50 mL solution (0.05 M in Co(NO3)2 and Cu(NO3)2). The subject of the investigation will include two different types of material with spun polyester between each layer sprinkled with less than 1.0 gram of sodium polyacrylate which will hypothesized the absorbency of a good amount of the 50 mL of solution; the value of this investigation included the possible solution to critical spills in the lab or in society. Experimental Design and Procedure This experiment involved the creation of two pillows crafted to be identical, but with differentiating amounts of sodium polyacrylate. The purpose of having sodium polyacrylate in the pillows is to aid in the absorption of the solution. To design and build the pillows, the micro punctured polypropylene and spun bounded polyester are to be cut into squares measuring 8cm x 8cm. The outer portion of the pillow was composed of the

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
