The Chemistry of Copper: AP Chemistry Lab Report

The lab was to include a purpose, procedure, data/observations, all reactions and topographic point reactions written out with qualitative data beneath singly product and reactant except H20, and a summary. The purpose of this experiment is to sugar the qualitative aspects of a series of reactions involving bull. Procedure 1.Measure about 1g of full-blooded copper. 2.Place Cu in Erlenmeyer flaskful and place flask at a lower place 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 content by slowly swirling flask. 7.Place flask back in peeing bath, heat to boiling, and stir. 8.Heat until separation of solid and resolution. 9.Cool flask and allow confine to settle. 10.De tin cant liquid from solid. 11.Wash solid with water and decant again. 12.Add 4M HCl until solid disappears, therefore add 1-2 ml excess. 13.Add 1g of aluminum to flask. Data/Observations 1.Start with 1g of orangish/ dye solid. 2.When HNO3 is added to Cu a dark chromatic gas is formed. 3.Clear, punt liquid forms when Cu is fully reacted. 4. secure blue light 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/ tan solid and clear, colorless solution is visible. Reactions 1. Cu + 4HNO3 = Orange/ dye consentient Clear, Co lorless liquidity 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, crystal clear Solid...
