Ionic compounds conduct electricity in molten state . Why?
Answers
Answer:
Explanation:
Ionic compounds are held together by many strong electrostatic forces between the oppositely charged ions. A lot of energy is needed to overcome these ionic bonds, so ionic compounds have high melting points.
A substance can conduct electricity if:
it contains charged particles, and
these particles are free to move from place to place
Ionic compounds conduct electricity when molten (liquid) or in aqueous solution (dissolved in water), because their ions are free to move from place to place. Ionic compounds cannot conduct electricity when solid, as their ions are held in fixed positions and cannot move.In molten state or dissolved state ionic compounds conduct electricity because they contain charged particles called cations and anions. These ions are free to move to conduct electricity. There are plenty of free ions in the molten state or dissolved state which are able to conduct electric current.
HOPE THIS TOTALLY HELPS YOU...
