Why does an ionic compound conduct electricity?

Answer:

A solution of ionic compounds in water contains ions, which moves to the opposite electrodes when electricity is passed through the solution. Therefore, ionic compound conducts electricity.

  • Ionic compounds in the solid-state do not conduct electricity because ions in the solid are not possible due to their rigid structure.
  •  Ionic compounds conduct electricity when molten (liquid) or in an aqueous solution because their ions are free to move from place to place.

Ionic compounds

Ionic compounds can be defined as crystalline solids formed by neatly packed ions of opposite charge. Ionic compounds are usually formed when metals react with non-metals.

Properties of ionic compounds

The properties of ionic compounds are

  • They form crystals.
  • They have high melting points and high boiling points.
  • They have higher enthalpies of fusion and vaporization than molecular compounds.
  • They’re hard and brittle.
  • They conduct electricity when they are dissolved in water.
  • They’re good insulators.
