What is a substance called if it contains free ions and conducts an electric current?

AAn insulator
BA precipitate
CA non-metal
DAn electrolyte
Answer & Solution
Correct answer: D. An electrolyte
1. A current needs charged particles that are free to move. 2. An electrolyte is a substance that contains free ions and behaves as an electrically conductive medium. 3. Sugar dissolved in water forms no ions, so it does not conduct and is a non-electrolyte. _Source: Siyavula Physical Sciences Grade 10 (Everything Science, CC BY 4.0), Chapter 18: Reactions in aqueous solution_
