Introduction: The purpose of an acid-base titration is to find the unknown concentration of one solution by using a solution of known concentration. An acid is a proton donor, while a base is a proton acceptor. There are three main types of acids known as monoprotic, diprotic and triprotic acids. Monoprotic acids contain one mole of H+ ions, per mole and will neutralize one mole of hydroxide, OH- ions. Diprotic acids contain two moles of H+ ions, per mole and will neutralize two moles of hydroxide, OH- ions. Subsequently, triprotic acids contain three moles of H+ ions, per mole and will neutralize three moles of hydroxide, OH- ions. The acid used in this experiment was oxalic acid and the unknown acid. The base used in this experiment was sodium hydroxide (NaOH). In this experiment oxalic acid was used to determine the concentration of

    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.
