Re: Bronsted and Lewis Acid/Base
The Bronsted definitions focus on protons and the Lewis definitions focus on electron pairs. The Bronsted definitions are more restrictive because they only consider the donating or accepting of a proton, whereas the Lewis definitions apply to any species that accepts or donates an electron pair.
Bronsted acid: proton donor
Lewis acid: species that accepts electron pair
Bronsted base: proton acceptor
Lewis base: species that donates electron pair
Bronsted acid: proton donor
Lewis acid: species that accepts electron pair
Bronsted base: proton acceptor
Lewis base: species that donates electron pair

Thanks for your response! Is there a way to tell if an acid or base is a Bronsted or Lewis if we're just given the chemical formula?

Re: Bronsted and Lewis Acid/Base [ENDORSED]
In the case that you are just given a formula, create a lewis dot structure for the molecule. From there, determine whether the molecule is proton or electron donor and label it as a Bronsted or Lewis acid or base. Drawing out the dot structure can indicate this by having lone pairs for example.
