Bronsted or Lewis Definition?

[Alan Wu]

For the upcoming final, which definition of acids and bases are we supposed to use by default?

Also, for Bronsted Bases, are we allowed to refer to NaOH (the entire compound) as a base? Or do we have to specifically point out that OH- is the Bronsted Base while Na+ is just a spectator ion?

I believe for the final we will have to know both the bronsted and lewis definitions since we went over both in lecture.

I would say that just to be safe, we should specifically point out that OH- is the Bronsted base and Na+ is a spectator ion.

[John Arambulo 1I]

NaOH, the entire compound, is considered a base (a STRONG base, even). A bronsted base is defined as anything that accepts a proton.

But the textbook explicitly states that Na+ is the spectator ion and OH- alone is the Bronsted Base. It warns us to not confuse it with what you said about NaOH being a Bronsted Base as a whole. But then many chemists just generally refer to NaOH as a whole being the Bronsted Base.

Read carefully please. I didn’t say that NaOH is a bronsted base as a whole, I said that that compound NaOH is a base.

That's literally the same thing...
