Advantages of Bronsted-Lowery Concept over Arrhenius Concept:
1. It can explain the basic character of substances like Na2CO3 i.e. which do not contain OH– group and hence were not bases according to Arrhenius concept on the basis that they accept protons.
2. This concept is not limited to molecules but also covers even the ionic species to act as acids or bases.
3. It can also explain the acid-base reactions in the non aqueous medium.
Limitations of the Bronsted-Lowery concept:
1. It cannot explain the reactions between acidic oxides like CO2, SO2, SO3 etc. and basic oxides like CaO, BaO, MgO, etc. which take place even in the absence of the solvent.
2. Substances like BF3, AlCl3, etc. behave as acids but they do not have protons to loose or donate.
