Here's why:
* Electrolysis is the process of using an electric current to drive a non-spontaneous chemical reaction.
* In electrolysis, the electric current provides the energy needed to break chemical bonds in the substance.
* This results in the decomposition of the substance into its constituent elements or simpler compounds.
Example:
The electrolysis of water (H₂O) uses an electric current to split water molecules into hydrogen gas (H₂) and oxygen gas (O₂).
Key points to remember about electrolysis:
* It's a non-spontaneous process, meaning it requires external energy (the electric current).
* The reaction occurs at the electrodes, which are submerged in the solution containing the substance being electrolyzed.
* The type of reaction that occurs at each electrode (oxidation or reduction) depends on the specific substance being electrolyzed.
