State the general properties of ionic compounds and covalent compounds.

General properties of ionic compounds:
  • Solid at room conditions.
  • High melting point and boiling point.
  • Soluble in water but insoluble in non-polar solvents.
  • Do not conduct electricity in the solid state.
  • Conduct electricity in molten state or in aqueous solutions.

General properties of covalent compounds:
  • Low boiling point and melting point.
  • Insoluble in water but soluble in non-polar solvents.
  • Do not conduct electricity, either in the solid or molten state.
