PROPERTIES OF IONIC COMPOUND

PROPERTIES OF IONIC COMPOUND

  • Physical nature: Ionic compounds are solids and hard because of the strong force of attraction between the positive and negative ions.
  • These compounds are generally brittle and break into pieces when pressure is applied.
  • Melting and Boiling points: Ionic compounds have high melting and boiling points because a high amount of energy is required to break the strong inter-ionic attraction.
  • Solubility: Electrovalent compounds are generally soluble in water and insoluble in solvents such as kerosene, petrol, etc.
  • Conduction of Electricity: A solution of an ionic compound in water contains ions, which move to the opposite electrodes when electricity is passed through the solution.
  • Hence they conduct electricity in the molten state.
  • Ionic compounds in the solid state do not conduct electricity because movement of ions in the solid is not possible due to their rigid structure.
