Question

An electrolyte is:
A. A cell
B. A metal
C. A liquid that conducts electricity
D. Sugar

Answer 1

An electrolyte is formed when two or more ions combine to form a neutral molecule. The property of an electrolyte is that it dissociates into its constituents when it is put into water. These ions contain charges on them.

Complete step by step answer:
We know about solid materials that conduct electricity. Meaning they allow the charges (electrons) within them to flow through them when a potential difference is created across them by connecting a cell.

There are liquids also that conduct electricity. These liquids are called electrolyte. This means that when a cell is connected across the electrolyte charges flow in the circuit.

An electrolyte is a liquid that dissociates when it is poured into water. The meaning of dissociation of an electrolyte is that the electrolyte forms its constituent ions.

An electrolyte is formed when two or more atoms form an ionic bond. For example, hydrogen chloride (HCl). A molecule of hydrogen chloride is formed when an ion of hydrogen with +1e charge combines with an ion of chlorine with -1e charge.

Therefore, when hydrogen chloride is put into water, it separates into the respective ions of hydrogen and chloride from which it is formed. Hence, the solution of electrolyte contains charges in the form of ions. Therefore, when a cell is connected to the solution, the ions (charges) respond to the potential difference and thus there is a flow of charges in the circuit. In this way, an electrolyte conducts electricity.
Hence, the correct answer is option C.

Note:
Do not misunderstand that conduction electricity means flow of electrons only. Conduction of electricity means obtaining a current in the circuit and current is equal to the amount of flow of charges in one unit of time. Therefore, electrons are not the only charges that exist. Ions also act as charges.
