Are Bronsted bases and acids determined based solely on if a proton is donated or accepted?

Yes. acids donate a proton while bases accept protons for bronsted definitions

Yes, a Bronsted base recieves a proton and a Bronsted acid donates a proton

Hi,

I agree with the statement above, and would like to add that this differs from the Lewis definition which discusses the transfer of electrons (acids- electron pair acceptor vs. base-electron donor).

Yes, bronsted definitions are based on proton accepting or donating (in contrast to lewis definitions based on electron accepting and donating).

Yes, for Bronsted Acids and Bases, we talk about the reaction of a molecule in regards to H+.
If a molecule donates H+, that is a Bronsted Acid (proton donor)
If a molecule accepts H+, that is a Bronsted Base (proton acceptor)
