Purpose : To predict how the equilibrium of a chemical reaction will be maintained when certain aspects of the reaction are changed. Procedure: 1. Two water baths, one hot and one cold, were prepared. Part I 1. 2 test tubes were labeled NaHSO 4 and Na 2 SO 4 2. The NaHSO 4 test tube was filled with approximately 5 mL of NaHSO 4 solution 3. The Na 2 SO 4 test tube was filled with approximately 5 mL of Na 2 SO 4 solution 4. 10 drops of NaHSO 4 solution were put in wells A1, A2, and A3 5. 20 drops of NaHSO 4 solution were put in wells A4 and A5 6. 1 drop of thymol blue was added to wells A1-A5, the color was recorded 7. Drops of Na 2 SO 4 were added to well A1 until a color change appeared, the color was recorded 8. Crystals of NaHSO 4 were added to well A3 until a color change appeared, the color was recorded 9. The solution from well A4 was inverted into a beral pipet and placed into the hot water bath and the cold water bath separately. The color was recorded 10.The solution from well A5 was inverted into a beral pipet and placed into the cold water bath and the hot water bath separately. The color was recorded Part II 1. Approximately 5 mL of 1.0 M MgCl 2 solution was placed into a labeled test tube 2. 20 drops of the solution were added to wells B1-B4 3.

    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.
