These copper (Cu) metal electrodes are made of high purity copper metal. Each copper electrode is stamped with letters "Cu" for easy identification. Copper electrodes are used for science experiments such as demonstration of Lenz’s law, making a voltameter, make electricity from fruits, and making electricity using other chemical reactions.
Copper electrode sheets are always a valuable addition to your collection of metals.
CAUTION: Metal electrodes have sharp edges.
Copper is reddish and takes on a bright metallic luster. It is malleable, ductile, and a good conductor of heat and electricity (second only to silver in electrical conductivity).
The electrical industry is one of the greatest users of copper. Iron's alloys -- brass and bronze -- are very important: all American coins are copper alloys and gun metals also contain copper. Copper has wide use as an agricultural poison and as an algaecide in water purification. Copper compounds, such as Fehling's solution, are widely used in analytical chemistry tests for sugar. Copper carbonate is green from which arises the unique appearance of copper-clad roofs or domes on some buildings. Copper oxides form the basis of many unconventional superconductors.
A good experiment and project is to use these (along with Zinc Electrodes) to produce electricity from fruits.
