Limitations of Arrhenius theory :
1. This theory is applicable only for aqueous solutions and not for non-aqueous solutions.
2. It fails to explain the acidic nature of non-hydrogen compounds like BF3, AlCl2, FeCl3, etc.
3. It fails to explain the basic nature of non-hydroxy compounds like NH3, amines, Na2CO3, KCN, aniline, etc. in their aqueous solutions.
4. It does not explain role of solvent or existence of H3O+ in an aqueous solution of an acid.
