So, they do not conduct electricity well. Conduction in liquids: Molten metal’s and mercury (a liquid metal) conduct electricity. The current through them is constituted by the flow of electrons. Other liquids conduct electricity because they have ions. What are
11.2 Electrolytes – Chemistry
The water molecules play an essential part in forming ions: Solutions of hydrogen chloride in many other solvents, such as benzene, do not conduct electricity and do not contain ions. Hydrogen chloride is an acid , and so its molecules react with water, transferring H + ions to form hydronium ions (H 3 O + ) and chloride ions (Cl − ):
