How to identify a Bronsted acid or base

[Alexander Hari 1L]

Can anyone offer some tips/examples on how to identify if a molecule is an acid or a base specifically Bronsted protons?

Atoms that donate protons are acids, and atoms that accept protons are bases. Hope this helps!

What exactly does the term Bronsted imply?

[Jade Corpus-Sapida 1G]

I would imagine from our lecture notes, that Bronsted refers to protons either being donated (acid) or accepted (base). While lewis refers to electrons.

[Luis Avalos 1D]

Bronsted acids donate protons (H+) while bronsted bases accept protons.

I think bronsted comes from the name of the guy who came up with the idea. kind of like schrodinger's equation. I could be mistaken though

How can you tell if it is a Bronsted acid or base without the reaction though? For example, on J1, you are asked to identify if it is a Bronsted acid or base just by the compound. How would you do this?

I'm also confused on how to do this. How can we tell whether or not a hydrogen has been donated or accepted with just the compound name? Will we be expected to do this on the final?

so what is the difference between Bronsted acid and bases vs lewis acids and bases?

[Jocelyn Fermin1J]

I believe we will have to identify the Bronsted acid/base and Lewis acid/base in reactions, but not through their name. For J1 you can create your own reaction since they are in a solution of water.
ex
HNO3 + H20 -> NO3^- + H30^+
acid base conjugate base conjugate acid

Therefore, HNO3 is a Bronsted acid.
can't be Bronsted base because

HNO3 + H20 -> H2N03^+ + OH^-
base acid conjugate acid conjugate base

this website helped me out a bit:

hope it will too!

Bronsted acids/bases are proton donors/acceptors.
Lewis acids/bases are electron acceptors/donors.

Bronsted and Lewis are scientists who proposed these ways of classifying acid/bases.
