Introduction: The aims of the experiment were to test the presence of sulfate ( 2 ¿ SO 4 ¿ ), chloride ( ¿ Cl ¿ ), carbonate ( 2 ¿ CO 3 ¿ ), bromide ( ¿ Br ¿ ), and nitrate ( ¿ NO 3 ¿ ) anions in an anions solutions, and to determine the anions present in an unknown solution of anions. Used equipments: Centrifuge tube Michrome wire loop Beaker Dropper Centrifuge Used chemicals: Hydrochloric acid solution (6M) BaCl 2 solution (0.1M) Anions solution containing sulfate ( 2 ¿ SO 4 ¿ ), chloride ( ¿ Cl ¿ ), carbonate ( 2 ¿ CO 3 ¿ ), bromide ( ¿ Br ¿ ), and nitrate ( ¿ NO 3 ¿ ) Unknown solution of anions Distilled water Ba ( OH ) 2 solution (0.1M) Sulfuric acid solution (3M, 18M) AgNO 3 solution (0.1M) Ammonia solution (3M) FeSO 4 solution Reactions: 1. + ¿ 2 H ¿ + 2 ¿ CO 3 ¿ CO 2 ( g ) + H 2 O 2

    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.
