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

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

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

Re: How to identify a Bronsted acid or base
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?

Re: How to identify a Bronsted acid or base
so what is the difference between Bronsted acid and bases vs lewis acids and bases?

Re: How to identify a Bronsted acid or base
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
ex
HNO3 + H20 -> NO3^- + H30^+
acid base conjugate base conjugate acid
Therefore, HNO3 is a Bronsted acid.

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

this website helped me out a bit:

hope it will too!
Re: How to identify a Bronsted acid or base
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.
