Electrolyte vs. Electrolysis: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on December 18, 2023
Electrolyte is a substance that produces ions when dissolved in a solvent, conducting electricity. Electrolysis is a process using electric current to induce chemical reactions, often to decompose substances.

Key Differences

Electrolytes are substances that, when dissolved in water or another solvent, dissociate into ions, thus becoming capable of conducting electricity. In contrast, electrolysis is an electrochemical process where electrical energy is used to drive a non-spontaneous chemical reaction, typically involving the decomposition of substances.
In the human body, electrolytes such as sodium, potassium, and calcium play crucial roles in maintaining vital functions by conducting electrical impulses. On the other hand, electrolysis is often used industrially, such as in the extraction of metals from ores or the production of hydrogen and oxygen from water.
Electrolytes are categorized based on their ability to form cations (positive ions) and anions (negative ions) in solution, essential for various biological and chemical processes. Electrolysis, however, involves applying an external electric current to an electrolytic cell to cause a chemical transformation, such as metal plating or water splitting.
The concentration and balance of electrolytes are vital for maintaining health, as imbalances can lead to conditions like dehydration or electrolyte disturbances. Electrolysis, in contrast, requires careful control of electrical current and potential to achieve desired chemical changes, such as in electroplating or electrolytic refining.
In batteries, electrolytes are used as a medium to transport ions between electrodes, enabling the flow of electric current. Electrolysis finds its application in battery technology too, particularly in the recharging process of secondary batteries, where chemical energy is converted back to electrical energy.
