The product made during this experiment was the chromium oxalate complex, K 3 [Cr(C 2 O 4 ) 3 ]*3H 2 O. During filtration of the product, a gap developed between the filter paper and the funnel bottom, allowing the crystallized solid to escape into the solution. Due to water being added to rinse the beaker, the chromium complex was now dissolved in a much larger amount of water, and it was not possible to recrystallize the solid even by chilling in an ice bath. As a result, another group's data had to be used for analysis. The calculated yield of the product was 98.02%. This is close to the theoretical maximum of 100%, indicating that the reactants were reacted almost completely and in correct stoichiometric ratios. The small difference could be caused by the slow rate of reaction 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.

    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.
