Expert Answer:

Compounds which gives different ions in solution although they have same composition are called ionisation isomerism.

This form of isomerism arises when the counter ion in a complex salt is itself a potential ligand and can displace a ligand which can then become the counter ion.

An example is provided by the ionisation isomers [Co(NH3)5SO4]Br and [Co(NH3)5Br]SO4.

Another example is, [Pt(NH3)4(OH)2]SO4 and [Pt(NH3)4SO4](OH)2.
