Writing a lab report

Electrochemistry Lab

Summary: This lab will guide you to use electrolysis to make metal solutions and electrodes. The voltage between electrodes and solutions will be observed. A concentration cell will be built and the error in voltage observations will be noted.

There are 4 copper electrodes packed with the graphite pencil “lead” sticks. In that container is also 8 pieces of iron wire. That wire may be coated with a thin layer of copper. Rub it off with sandpaper, nail file, or rough paper towel. You need the black or shiny silver-colored metal underneath. Please see those video for help
