Be very careful with the acid! It is damaging to your skin. If it spills on you or your lab bench, notify your instructor. 3. Place your reaction beaker on the hot plate, turn to LOW, and gently heat the mixture in your beaker to 40 °C on a hot plate. Monitor the temperature with a thermometer, but DO NOT leave the thermometer in the beaker suspend it in your solution to record the temperature, then remove it. Heat for a total of 10 minutes, stirring constantly with a glass stirring rod NOT the thermometer. Maintain a temperature near 40 °C, by adjusting the heat control on the hot plate. Note any observations. The reaction occurring here is CuO (s) + 2 HCl (aq) CuCl 2 (aq) + H 2 O (l) 4. Remove the beaker from the hot plate using beaker tongs, and set it on the lab table. 5. Obtain a piece of solid zinc metal. Record initial observations of the metal. Then, place the zinc in the solution. Record your observations of the metal-replacement reaction. It is important to write down observations here! 6. Once you have detailed observations, and are satisfied your data table is complete, place your beaker in the area designated by your instructor. 7. Wash your hands. We will return to the lab next time, to complete the retrieval of copper metal.

Day Two Removing the copper metal from the surface of the zinc 8. Obtain your reaction beaker. Record visual observations , and compare to your previous-day observations. Using a scoopula and forceps, carefully scrape the newly-formed copper from the zinc, collecting it in the beaker. A wash bottle may also be useful - using a stream of water to remove the

    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.
