Unformatted text preview: 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 (I I) Nitrate and Copper (I I) 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. Part 2 Synthesis of Copper (I I) Oxide • Set up a heating apparatus. In this heating apparatus Cu (OH) 2 is put in a beaker, which is on a wire gauze supported by a ring clamp, that is heated...
