Patrick Henry AP Chemistry Students Extract Copper
Mon, October 3, 2016
Students in Mrs. Woosley’s AP chemistry class conducted a single replacement reaction experiment. In the lab, students removed the water from a mass of copper (II) chloride dihydrate, made a solution of the resultant anhydrous solid, and displaced the copper from solution using aluminum metal.
The products included copper metal, which was then filtered from solution and dried. The students had to determine the formula of the hydrate from the data and determine percent error based on the stoichiometry of the reaction and the actual yield of the copper metal. This lab requires the demonstration of numerous techniques and skills and encompasses the entirety of the stoichiometry concept in chemistry. Now, if we could only figure out what to do with all that copper…..
