Summary of Lab Procedure (Experiment #1) Part 1: Synthesis of Copper (II) Nitrate and Copper (II) Hydroxide 1. Get length of coper wire + piece of sand paper. 2. Sand wire 3. weigh wire on analytical balance and record on data sheet (4 decimal digits). a. To use analytical balance: i. Take weighing beaker, three clean Erlenmeyer flasks (250 mL) and data sheet to analytic balance weighing room. ii. For future handling of weighing beaker, use strip of strong paper as handle strap. iii. Place weighing beaker on analytic balance and close doors. iv. Record initial mass of weighing beaker on sheet as “mass of beaker plus sample” v. Remove beaker from balance. vi. Pour third of solid in flask #1. DO NOT SPILL. vii. Reweigh the weighing beaker and contents. If not enough is added, add more. viii. When desired weight has been transferred to flask #1, weigh beaker again and record data labelling it as “mass of weighing beaker minus sample #1” ix. Cover flask #1 and set aside x. Repeat for samples #2 and #3 4. Place copper wire in a 250mL beaker 5. In fume hood, add 10 mL of concentrated nitric acid. 6. Let Copper and Nitric acid sit until reaction is complete. 7. Observe and record observations of reaction on the Data sheet.

    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.
