State the general properties of ionic compounds.

1.	State the general properties of ionic compounds.
Answer» 1. Ionic compounds 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 kerosene and petrol. 5. Ionic compounds cannot conduct electricity when in solid state, they are electrically neutral. They conduct electricity in the molten state and also in an aqueous solution.
