Give evidence that `[Co[NH_3)_5Cl]SO_4` and `[Co(NH_3)_5SO_4]Cl` are ionisation isomers.

Explanation

The ionisation isomers dissolve in water to yield different ions and thus react differently to various reagents. Add .BaCl., solution. .[Co(NH_3)_5 Cl] SO_-. will give. white precipitate due to formation of .BaSO., whereas
Add AgNOP, solution. [CO(NH, )SO ] CI will give white precipitate due to formation of .AgCI. whereas .[CO(NH_3)_3 Cl] SO_4.. will not react.
It show that these isomers produces different ions in aqueous solution. but have, same chemical formula therefore they are ionization isomers.
