Experimental Procedure Summary Name: Niraj Patel ID# 20387356 TA: Chris Goudy Date: October 8 th , 2010 Experiment #1: The chemistry of copper compounds Procedure: Part 1: Synthesis of Copper (II) Nitrate and Copper (II) Hydroxide Pick up copper wire and piece of sandpaper from the side bench Sand the wire Weigh the copper wire on analytical balance (masses quoted to 4 decimal place) Place copper wire in a 250 ml beaker, and place in fume hood In fume hood add 20ml of concentrated nitric acid, HNO 3 to the beaker Let nitric acid and copper wire sit in the fume hood until the reaction is complete Observe and record a description of this reaction After the wire has dissolved swirl reaction mixture in fume food to remove gases trapped in the solution before taking the beaker to your desk Keep in fume hood until solution is bright blue After dissolution, dilute with 25ml of deionized water( water from grey taps located beside the fume hoods) While stirring slowly add 25ml of 20 percent NaOH. Adding 25ml of 20 percent NaOH should make the solution alkaline. Observe and record a description of this reaction.

    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.
