An ionic compound conducts electricity when it is
Answer and explanation
Correct answer: C. molten or dissolved in water
- Step 1: Conduction needs mobile charge carriers, which ions become when the lattice breaks down.
Answer
molten or dissolved in water.
Why not the others: a solid crystal: ions are held in fixed positions in the solid. a solid at room temperature but not when molten: the ions can move when molten, so it does conduct. never: when molten or dissolved the ions become free to move.
