(v) What is meant by an ionic compound? State the general properties of ionic
compound?
Answers
Answer:
Ionic Compounds have high boiling and melting points as they're very strong and require a lot of energy to break. The electrostatic forces of attraction between oppositely charged ions lead to the formation of ions. Ionic compounds form crystals. These compounds are brittle and break into small pieces easily.
Ionic compounds typically have high melting and boiling points, and are hard and brittle. As solids they are almost always electrically insulating, but when melted or dissolved they become highly conductive, because the ions are mobilized.
General properties of ionic compounds:
(1) ionic comopound are solids and hard due to strong electrostatic force of attraction between oppositely charged ions.
(2) They are generally brittle. When pressure is applied they break into pieces.
(3) They have high melting and boiling points, due to intermolecular force of attraction is high in ionic compounds.
(4) They are soluble in water and insoluble in solvents such as keerosen and petrol.
(5) Ionic compounds cannot conduct electricity when in solid state, they are electrically netural. They conduct electricity in the molten state and also in an equeous solution.
