Ionic compounds are compounds that are formed as a result of ionic bond between metal and non-metal. This occurs as a result of transfer of electrons between the atoms involved where one losses electrons to form a cation and the other gains electrons to form an anion.
Most bases like the ionic compounds they contain a cation and an anion, which forms a compound.
An example would be: KOH (potassium hydroxide) and Ca(OH)2 is calcium hydroxide.
