Ionic compounds are diverse in nature and form.

Here are some of their properties:

  • They are usually hard solids with a high melting point or liquids with high boiling points
  • They are soluble in water and non-soluble in non-polar solvents
  • They are able to conduct electricity in molten form.
  • They undergo very fast reaction in aqueous solutions.
