Question
State the general properties of ionic compounds.
✓
Answer
- Ionic compounds are solids and hard due to strong electrostatic force of attraction between oppositely charged ions.
- They are generally brittle. When pressure is applied they break into pieces.
- They have high melting and boiling points, due to intermolecular force of attraction is high in ionic compounds.
- They are soluble in water and insoluble in solvents such as kerosene and petrol.
- 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.
