 So in this problem, it wants us to identify that acid base and conjugate acid conjugate base, okay? So we need to identify all four of those things. So where are the acid and base going to be and where are the conjugate acid and conjugate base going to be? So the acid and base, are they going to be on the left or the right here? The left because that's what you start with, okay? Always with the acid and base. Okay, so now we've got to figure out which one of these things is the acid and which one of them is the base. These ones aren't the easiest one to figure out because there's no hydroxide and you know that type of thing, but we can look over to here and see what happened to them. Does everybody understand what I'm saying? So help me out. What is this? The acid or the base? This is acetic acid, okay? The acetic acid is the acid, yes. Okay, how did I know that? Because when I look over here, right, I removed an H plus. Does everybody see that? Okay, so since that's the acid, this must be the one. The base. The base, okay? This thing over here is called the what? Conjugi base. Conjugi base, very good. And this one? Conjugi acid. So again, you just look out the react and see what happened to them on the products and from there you can identify what's my acid, what's my base, and how don't you get acid, don't you? Is everybody okay with doing something like this? Any questions? Okay, sorry to bore you guys, but we do have to do this one. Okay, pretty basic though.
