On Capillary Rise and Nucleation R. Prasad
A comparison of capillary rise and nucleation shows that both phenomena result from a balance between two competing energy factors: a volume energy and a surface energy. This comparison may help to introduce nucleation with capillary rise, a topic familiar to students.

Copper Metal from Malachite circa 4000 B.C.E. Gordon T. Yee, Jeannine E. Eddleton, and Cris E. Johnson
The experiment starts with a naturally occurring ore, malachite, essentially pure Cu2CO3(OH)2, which is readily available at modest cost in bead form from jewelry stores. Using only a Bunsen burner, a porcelain crucible, and a charcoal briquette, the experiment demonstrates two steps in the ancient processing of copper ore: roasting and reduction. The product is a shiny copper metal bead that can then be hammered, polished, and shown to be electrically conductive.

Isolation of Copper from a 5–Cent Coin. An Example of Electrorefining Steven G. Sogo
The United States 5cent coin, commonly known as a "nickel", is made of an alloy containing 75% copper and 25% nickel. The experiment is a visually appealing illustration of the process of electrorefining using selective reduction.

Metallurgy in the Laboratory: Preparation of Pure Antimony Brooke L. O'Klatner and Daniel Rabinovich
The preparation of pure antimony is readily accomplished on a laboratory scale by the high-temperature reduction of antimony trioxide with potassium cyanide. The product is obtained in almost quantitative yield (up to 98%) using a procedure that is simple, inexpensive, and quick.

The extraction of gold and its simulation with copper Bradley, J. D.; Brand, M.; Louli, J. A. M.
The simulation of the extraction of gold by the use of its analog, copper, makes it possible to capitalize on the glamor of gold without sacrificing any chemical principles.

The identification of an unknown alloy. A first experiment in elementary chemistry Watson, Naola V.
The experiments which are often used as an introduction to the laboratory in beginning chemistry courses are considered by many students to be sheer buys work. This experiment is devised to provide students with an interesting and meaningful introduction to the laboratory.
