🔍 Key Concepts

• Electrolyte and how it behaves in solution • Difference between conductors, insulators, and materials that change chemically when current passes • Basic idea of electrolysis (chemical decomposition by electric current)

💭 Think About

• When a liquid conducts electricity and chemically decomposes, what process in chemistry/physics does that describe? • Which of the choices names a type of material that can be a conducting liquid involved in that process? • Do any of the other answers actually describe a liquid or a material in liquid form that changes during conduction?

✅ Before You Answer

• Check which option refers to a liquid substance that can carry electric current. • Eliminate any choice that clearly describes a solid magnetic material or a circuit property instead of a liquid. • Recall that the liquid used in electrolysis has a specific name—match that name to the options.
