Lab 6 1. Obtain 400mL if sodium hypochlorite and 400 mL of sodium sulfite. Obtain two 100mL graduated cylinders, 2 thermometers, a stirring rod, and a calorimeter cup and thermometer cup. 2. Measure out the appropriate amount of each solution 3. Place a thermometer in each solution. If the solutions are not equivalent, wait until the temperatures equilibrate 4. Place the thermometer from one solution into the calorimeter cup and have the clip hold the thermometer. Place the thermometer inside the ring on the ring stand for support. 5. Add one solution to the calorimeter cup and record the initial temperature in the data sheet. 6. Pour the second solution to the same calorimeter cup and immediately start stirring.

If the two lines create an inverted “v” shape, conTnue. 10. Use the intersecTon point to determine the stoichiometric raTo. 11. Drop a line down and see where it crosses each x-axis. ±his will tell you how many moles of each substance is needed. 12. Calculate the number of moles of reactant. Moles = molarity x volume. 13. Calculate the change in temperate. ±his is the Fnal temperature – the iniTal temperature....

    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.

    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.
