|
Definition |
Electrode where reduction (gain of electrons) occurs |
Electrode where oxidation (loss of electrons) occurs. |
|
Electron Flow |
Electrons flow into the cathode from the external circuit. |
Electrons are released from the anode into the external circuit. |
|
Charge Accumulation |
Accumulates a positive charge. |
Accumulates a negative charge. |
|
Function in Cells |
Consumes electrons during a spontaneous electrochemical reaction. |
Produces electrons during a spontaneous electrochemical reaction. |
|
Direction of Current Flow (Conventional) |
From cathode to anode. |
From anode to cathode. |
|
Example |
In a battery, the cathode is where reduction occurs during discharge. |
In a battery, the anode is where oxidation occurs during discharge. |
Cathode and Anode
Cathode and Anode are commonly used terms in the context of electrochemistry, specifically in electrochemical cells like batteries and electrolytic cells. An anode is a negative or reducing electrode that releases electrons and oxidizes during an electrochemical reaction whereas a Cathode is a positive or oxidizing electrode.
In this article, we will learn about, Cathode, Anode, their differences, and others in detail.
