PURPOSE The purpose of this experiment is to understand the reactivity of several substances that will later help identify unknown reagents. The mixing of two reagent solutions will be done systematically and any reactions will be noted. The color of precipitates, color changes, and odors will help identify the formation of complexions/soluble compounds, acid-base reactions, and potential oxidation reactions. Then the unknown reagents will be mixed with the known reagents and the resulting properties will help to identify the unknowns. PROCEDURES A matrix will be created with the various solutions used. Mixing of these two solutions will be done by placing one drop of each of the solutions with a medicine dropper. The physical changes of these reactions will be recorded. Then a new matrix is created and the same procedures are repeated and compared with the original matrix to identify the unknown reagents. All substances will be obtained from pre-prepared supplies.

    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.
