Final answer:
Electrical current that produces chemical action is used in electrolysis, a part of electrochemistry, where electricity drives non-spontaneous chemical reactions through redox processes.
Step-by-step explanation:
The kind of electrical current that produces a chemical action is involved in the process of electrolysis. Electrolysis is a chemical process where electrical energy is used to drive a non-spontaneous chemical reaction. This is a fundamental concept in the field of electrochemistry, which focuses on the interconversion of chemical energy and electrical energy. In electrochemical reactions, electricity is used to cause a redox reaction, in which electrons are transferred from one substance to another, ultimately leading to chemical changes. For example, when electricity is passed through a solution containing ions, these ions can be driven to move towards electrodes, undergoing chemical reactions that release or consume electrons, subsequently changing the material at the electrodes or the solution itself.
Batteries are a common application of electrochemistry, where chemical reactions within the battery produce electrical energy. In contrast, in electrolysis, an outside source, such as a battery, provides the energy necessary to create a separation of charge and induce chemical changes, which does not occur spontaneously.
