MATERIALS • Copper sulfate electrolyte solution (200 g CuSO4· 5H2O + 25.0 mL concentrated H2SO4 solution in enough distilled or deionized water to make 1.0 L of solution) • Coin cleaning solution (1 tsp table salt dissolved in 1⁄4 cup vinegar) • Pre-1982 penny (contains 95% copper, versus only 2.5% copper post-1982) Figure 1: Materials needed for copper electrolysis lab. • Dime (any year) • 9V battery (use a new 9V battery for each experiment) • 18-gauge copper wire • Four alligator clips (2 each of red and black) • Wire stripper and needle-nosed pliers • Two 250-mL beakers • Cardboard circle (approx. 15 cm diameter) • Precision scale (optional) SAFETY PRECAUTIONS Gloves and goggles should be worn throughout this experiment. Sulfuric acid can cause burns so please handle with care. Although the power source is relatively weak, the electrodes and connecting wires should not be handled when the cell is operating. The 9V battery can become quite hot during use; use caution when handling it. PROTOCOL 1. Clean the penny with salt/vinegar mixture; rinse with water and dry (dime does not need to be cleaned). 2. Prepare the wire assembly: a. Cut a 33 cm length of 18-gauge copper wire (Figure 2). 33cm Figure 2. 33 cm length of 18-gauge copper wire.PDF Image | Chemistry of Copper Electrolysis
