The Chemistry of Copper: AP Chemistry Lab Report

The lab was to include a purpose, procedure, data/observations, all replys and furrow reactions written out with qualitative data beneath distributively product and reactant except H20, and a summary. The purpose of this experiment is to dough the qualitative aspects of a series of reactions involving bull. Procedure 1.Measure about 1g of red-blooded bulls eye. 2.Place Cu in Erlenmeyer flaskfulful and blank flask under 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 micturates. 6.Mix confine by slowly swirling flask. 7.Place flask back in piss bath, heat to boiling, and stir. 8.Heat until separation of unassailable and re solvent. 9.Cool flask and allow content to settle. 10.Decant luculent from potent. 11.Wash solid with irrigate and decant again. 12.Add 4M HCl until solid disappears, then add 1-2 ml excess. 13.Add 1g of aluminum to flask. Data/Observations 1.Start with 1g of orangish/bronze solid. 2.When HNO3 is added to Cu a dark chromatic gas is formed. 3.Clear, game liquid forms when Cu is fully reacted. 4. mend blue precipitate forms when NaOH is added. 5.When heated, settlement 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/bronze solid and clear, colorless solution is visible. Reactions 1. Cu + 4HNO3 = Orange/ tan unattackable Clear, Colorless Liquid Cu(NO3) 2 + 2NO2 + 2H2O Clear, Blue Liquid reddened/ 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, gossamer Solid...
