Which one do we use in lecture most often, and is it necessary to specify on exams?

I believe you should be able to know what the difference is between the two for the exam.

You'll probably want to know the definitions of both and be able to identify them based on a reaction equation or when given a certain experimental context, but it's likely that the question will explicitly ask you to state whether something is a bronsted/lewis component.

By the Bronsted definition, an acid is a proton (H+ ion) donor and a base is a proton acceptor while by the Lewis definition, an acid is an electron acceptor and a base is an electron donor.

In the book it mentions that when they say 'acid' they are referring to the Brønsted acid so I'm assuming that applies for lecture as well. I think if he were to mention lewis acids/bases he would say 'lewis acid' or 'lewis base'. And I would definitely know how to differentiate the two for the final!
