In the electrochemical cell, which electrode is the site of reduction? (2023)

Step 1: Understand what an electrochemical cell is. It is a device that converts chemical energy into electrical energy.
Step 2: Identify the two electrodes in an electrochemical cell: the anode and the cathode.
Step 3: Know that reduction is a chemical reaction where a substance gains electrons.
Step 4: Remember that in an electrochemical cell, the cathode is the electrode where reduction takes place.
Step 5: Conclude that the cathode is the site of reduction in an electrochemical cell.

Electrochemical Cells – Electrochemical cells consist of two electrodes, the anode and cathode, where oxidation and reduction reactions occur.
Reduction – Reduction is the gain of electrons, which occurs at the cathode in an electrochemical cell.
Cathode vs. Anode – Understanding the difference between the cathode (site of reduction) and anode (site of oxidation) is crucial.
