 Copper–copper(II) sulfate electrode

The copper-copper(II) sulfate electrode is a type of reference electrode commonly used in electrochemistry. It consists of a copper metal electrode immersed in a saturated solution of copper(II) sulfate (CuSO₄). This electrode is popular because it provides a stable and reproducible electrochemical potential, making it useful in various applications, including corrosion studies and as a reference in potentiometric measurements.
