This copper plate is designed for use in simple electrochemical cell experiments. The plate measures 125mm x 50mm with a thickness of 1.5mm and is fitted with 4mm socket terminals for connection to external circuits. Copper serves as a common electrode material in galvanic and electrolytic cell demonstrations, where its electrochemical properties can be compared against zinc, iron, or other metal plates to illustrate voltage generation, electrode potential, and metal reactivity.
