Question

Name the electrode and the potential when the electrode reaction involves reduction.

Answer 1

When the electrode reaction involves reduction, the electrode is called a cathode, and the potential is known as the reduction potential.

Cathode: The electrode where reduction (gain of electrons) occurs.

Reduction potential: The potential associated with the reduction half-reaction at an electrode.

This is a fundamental concept in electrochemistry and is typically covered in the context of galvanic (electrochemical) and electrolytic cells.
