Which product relies on the ability of ionic compounds to conduct electricity?

• A. Gasoline engines in automobiles
• B. Solar panels for generating electricity
• C. Electrolytic cells used in metal plating
• D. Mechanical watches

Answer: (C)

Verified step by step guidance

1. Understand that ionic compounds conduct electricity when they are molten or dissolved in water because their ions are free to move and carry charge.
2. Recognize that electrolytic cells rely on the flow of ions to conduct electricity and drive non-spontaneous chemical reactions, such as metal plating.
3. Analyze each option: Gasoline engines do not depend on ionic conductivity; they rely on combustion of fuel.
4. Solar panels generate electricity through the photovoltaic effect, which involves semiconductors, not ionic conduction.
5. Mechanical watches operate through mechanical movement and gears, not electrical conduction by ions.
