Christmas Redox Ornament Lab
Name:___________________________________________________________
Purpose: plate a piece of galvanized metal with copper (Cu) through redox chemistry to make a decorative Christmas ornament. You
will make three ornaments: one for your family, one for Mrs. Chott, and one for a Christmas wreath that will decorate the halls of
SLUH.
Your grade will include the completion of three ornaments by Tuesday, Nov. 26 (worth 3/15 points).
This Lab Report due Thur. Nov. 21.
One extra point for each SLUH-themed ornament for Mrs. Chott (max. of 2 points)
Background: Galvanized metal is made of iron (Fe) coated with a layer of zinc (Zn). The zinc provides protection against rusting
(oxidation of the metals by water and oxygen in the air.) Redox chemistry can be used to remove the zinc layer that covers the iron and
replace the iron with copper.
Pre-lab work: You will have three 2 ½” x 2 ½” pieces of galvanized metal covered with masking tape. Create designs for each side of
the squares of metal (6 designs total). You may have the same design on each side, or two different designs. Simple designs are easiest
to prepare. Keep in mind where the hole is located for hanging. If you are not artistically inclined, and feel the need to trace your
design from a template, you may use several available templates. The inner portion of the design will be copper-colored on the finished
ornament. Or you may cut out the outline of the design so that the design is silver surrounded by a copper background.
