What is the term used for the chemical actions that occur due to an electrical current passing through certain matter?

The correct term for the chemical actions that occur due to an electrical current passing through certain matter is electrolysis. This process involves the breakdown of a compound into its individual components through the application of an electrical current.

During electrolysis, ions in an electrolyte move towards electrodes, leading to chemical reactions that result in the formation of new substances. This principle is fundamental in various applications, such as metal plating and water splitting, and highlights the relationship between electricity and chemical change.

The other options do not accurately describe this specific process. Pulsation refers to rhythmic variations, ionization involves the formation of charged particles from neutral atoms or molecules, and electromagnetism pertains to the behavior of electric charges in relation to magnetic fields. Hence, while these terms have their significance in the study of electricity and chemistry, they do not pertain to the chemical actions prompted specifically by an electrical current, which is why electrolysis stands out as the correct choice.
