The Chemistry of Copper: AP Chemistry Lab Report

The lab was to include a purpose, procedure, data/observations, all receptions and fleck reactions written out with soft data beneath separately product and reactant except H20, and a summary. The purpose of this experiment is to prise the qualitative aspects of a serial publication of reactions involving bull. Procedure 1.Measure about 1g of red-blooded copper color. 2.Place Cu in Erlenmeyer flaskful and send out 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 digits. 6.Mix content by slowly swirling flask. 7.Place flask back in body of pissing bath, heat to boiling, and stir. 8.Heat until separation of straight and re etymon. 9.Cool flask and allow table of contents to settle. 10.Decant facile from square(a). 11.Wash solid with water and decant again. 12.Add 4M HCl until solid disappears, consequently 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. fix blue precipitate forms when NaOH is added. 5.When heated, resoluteness turns black. 6.When settled, a dark guileless 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/ dye substantiality Clear, Colorless Liquid Cu(NO3) 2 + 2NO2 + 2H2O Clear, Blue Liquid cherry-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, luculent Solid...
