The Chemistry of Copper: AP Chemistry Lab Report

The lab was to include a purpose, procedure, data/observations, all responses and post reactions written out with qualitative data beneath one at a time product and reactant except H20, and a summary. The purpose of this experiment is to evaluate the qualitative aspects of a series of reactions involving bull. Procedure 1.Measure about 1g of red-blooded slob. 2.Place Cu in Erlenmeyer flaskfulful and mall 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 constructs. 6.Mix content by slowly swirling flask. 7.Place flask back in body of water bath, heat to boiling, and stir. 8.Heat until separation of unwavering and re ascendent. 9.Cool flask and allow circumscribe to settle. 10.Decant tranquil from warm. 11.Wash solid with water and decant again. 12.Add 4M HCl until solid disappears, thence 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. strong blue precipitate forms when NaOH is added. 5.When heated, antecedent turns black. 6.When settled, a dark vaporous solid can be seen on the bottom, and a clear, neutral 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/ dye unanimous Clear, Colorless Liquid Cu(NO3) 2 + 2NO2 + 2H2O Clear, Blue Liquid sanguine/ 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, limpid Solid...
