Arrhenius kind states that an acid/base reaction will constantly incorporate an H+ species and an OH-. Bronsted-Lowry states that a reaction is acid/base if it includes a proton donor and a proton acceptor. this may well be a extra super definition, as you do no longer want an OH-. Lewis acids states that acid/base reactions have electron pair acceptors and donators. it fairly is a amazing broader definition simply by fact it does not require the two H+ or OH-, so it may comprise so plenty extra reactions (gas-section acid/base reactions, as an occasion). For the occasion: HCl + H2O --> H3O+ + Cl- you will discover that H2O accepts the donated proton from HCl. on a similar time, H2O is the Lewis base considering that is accepting protons from HCl, that's the Lewis acid. It does not, inspite of the undeniable fact that, incorporate OH- species. So the reaction may well be seen a Bronsted-Lowry or a Lewis acid/base reaction.
