Acid-Base Extraction Jody Cho*, Jahra Batul, Vansi Ghandi, Mary Maliszewski (TA). Organic Chemistry I Laboratory, 3147 ISB, Department of Chemistry, University of Kansas. October 3, 2019. INTRODUCTION In this lab experiment, a liquid-liquid extraction was done to extract, isolate and obtain pure compounds. An acid-base extraction, a type of liquid-liquid extraction, was carried out to yield pure p-nitroaniline, benzoic acid and naphthalene. A liquid-liquid extraction is a method to separate compounds via partioning between two liquids. These two liquids are immiscible and create an aqueous layer and an organic layer. The aqueous layer is generally water and collects non- polar compounds while the organic layer collects polar compounds. In this case the organic layer was made up of ethyl acetate. During this acid-base extraction, organic compounds were exposed to sodium hydroxide (NaOH) and hydrochloric acid (HCl). When the compounds were exposed, they reacted in an acid-base reaction manner.

    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.
