$\left[\mathrm{Co}\left(\mathrm{NH}_{3}ight)_{5} \mathrm{Br}ight] \mathrm{SO}_{4}$ and $\left[\mathrm{Co}\left(\mathrm{NH}_{3}ight)_{5} \mathrm{SO}_{4}ight] \mathrm{Br}$ are example of which type of isomerism
Linkage
Geometrical
Ionization
Optical
Solution
The two given compounds have same composition but in solution both will give different
ions. This type of isomerism is known as ionisation isomerism.
