What is a solution that causes electrical conduction in liquids called?

The term used to describe a solution that causes electrical conduction in liquids is "electrolyte." An electrolyte is a substance that, when dissolved in a solvent (often water), dissociates into ions. These ions can move freely, allowing the solution to conduct electricity. This process is crucial in various applications, including batteries and electrochemical cells, where the movement of ions is essential for the flow of electric current.

In contrast, while a solvent is the base liquid that dissolves the electrolyte, it does not inherently conduct electricity. An oxidizer refers to a substance that can accept electrons during a chemical reaction but does not relate specifically to electrical conduction. A conductor typically refers to a material that allows the flow of electric current, such as metals, and is not specifically bound to the context of liquids as electrolytes are. Thus, "electrolyte" is the most accurate term for a solution that enables electrical conduction due to the presence of mobile ions.
