Mass of product done experimentally 0.41g Theoretical Mass 0.49984895g Percent Yield 82.02% Confidence Report To begin the lab, we my lab partners and I noted down the initial observations which consisted of granular zinc, iodine crystals, and deionized water. My partners and I were extra careful with our procedure and measuring. We made thorough observations and recorded exact data. We weighed and reweighed our substances and we confirmed with our peer groups about the accuracy with which we were performing our lab. Throughout the lab, we all kept all eyes and ears open as the other performed a part of the procedure and often double checked the observations with each other, our peers, and sometimes even the Professor Tam.

Natalia, Gabby, and I were all extra careful with all the steps we performed. For example, as I weighed the .45 g of Zinc Sulfate heptahydrate and .68 g of the Barium Iodide Dihydrate, I redid the weighing twice because the wind or even my own mistakes while decreasing the

    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.
