Leftover Aluminum Wire—A Stoichiometry Super Value Kit

By: Jeff Bracken, Westerville North High School, Westerville, OH

Item #: AP4678

Price: $29.15

In Stock.

With the Leftover Aluminum Wire Stoichiometry Laboratory Kit, students perform a reaction between aluminum wire and a copper salt. Students find the amount of aluminum that should react and compare to the amount of “leftover” aluminum.

Product Details

Here is an impressive and affordable lab activity that gives consistent results in just a matter of minutes! Students perform a redox reaction between aluminum wire and a copper(II) salt. The progress of the reaction is followed by observing the disappearance of the green-blue copper color and the formation of solid copper on the wire. Using stoichiometric calculations, students predict the amount of aluminum that should react and compare this value to the actual amount of “leftover” aluminum. Reproducible student handouts are included, providing a detailed procedure, data table, guided calculations and question sheets. Also included is an alternate set of handouts that gives a higher level, open-ended laboratory option in which students design their own data tables and work independently through the calculations. Teacher Notes provide sample data, calculations, teaching tips and answers to questions.

Super Value Kit is complete for 5 classes of 30 students working in pairs.

Performance Expectations

HS-PS1-2: Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
HS-PS1-6: Refine the design of a chemical system by specifying a change in conditions that would produce increased amounts of products at equilibrium.
HS-PS1-7: Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
