The Chemistry of Copper: AP Chemistry Lab Report

The lab was to include a purpose, procedure, data/observations, all reactions and blood line reactions written out with qualitative data beneath one after another product and reactant except H20, and a summary. The purpose of this experiment is to booty the qualitative aspects of a series of reactions involving bull. Procedure 1.Measure about 1g of red-blooded copper. 2.Place Cu in Erlenmeyer flaskful and place flask downstairs fume hood. 3.Add dropwise 15M HNO3 until unassailable copper is completely reacted. 4.Place flask in piss bath. 5.Add 4M NaOH slowly until no more substantiality forms. 6.Mix confine by slowly swirling flask. 7.Place flask back in water bath, heat to boiling, and stir. 8.Heat until separation of solid and resolution. 9.Cool flask and allow content to settle. 10.De throw outt liquid from solid. 11.Wash solid with water and decant again. 12.Add 4M HCl until solid disappears, hence add 1-2 ml excess. 13.Add 1g of aluminum to flask. Data/O bservations 1.Start with 1g of orangish/ bronzy solid. 2.When HNO3 is added to Cu a dark chromatic gas is formed. 3.Clear, second liquid forms when Cu is fully reacted. 4. secure blue shine forms when NaOH is added. 5.When heated, solution turns black. 6.When settled, a dark crystalline solid can be seen on the bottom, and a clear, colorless solution is on top. 7.When HCl is added, a bluish/green solution forms. 8.When solid Al is added, bubbles form and the intensity of the solutions color diminishes. 9.

When reaction is complete, orange/ dye solid and clear, colorless solution is visible. Reactions 1. Cu + 4HNO3 = Orange! / bronzy fast(a) Clear, Colorless fluidness Cu(NO3) 2 + 2NO2 + 2H2O Clear, Blue Liquid Red/ browned Gas 2. Cu(NO3)2 + NaOH = Clear, Colorless Liquid Cu(OH)2 + 2NaNO3 Blue, Solid Precipitate Clear, Colorless Liquid 3. Excess HNO3 + NaOH = NaNO3 + H2O 4. Cu(OH)2 + 2HCl = Black, cobwebby Solid...
