In order to earn the honors credit for the Spring 2023 semester, I made a contract with Ms. Nguyen for the CHEM-C 106 course to experimentally assess the soil health of IUPUI’s New York Street Urban Garden. I collected seven samples from the garden and performed a pH test, phosphate content test, and organic carbon test to determine the condition of the soil and how it could be improved to be suitable for the crops that are going to be planted later in the spring.
While I conducted the experiment, I learned how to use lab equipment such as a pipette, a pH meter, an analytical balance, and a spectrometer. Getting to practice using the equipment in lab is extremely beneficial for my future career in the field of chemistry since it will rely heavily on me being competent with the lab equipment. Overall, the honors contract course granted me the chance to acquire in-depth knowledge in my major field, gain hands-on chemistry lab experience, and form a strong, personal relationship with my professor, all of which are crucial for my personal growth and advancement in my academic and professional career.

Watch the color change carefully! The equivalence point of the titration between the diggested soil sample and 0.5M FeSO4 is when the solution changes from dark blue to a deep red.
