 Okay, so let's try this one that you guys are using. So, a lot of you want me to do. What's the conjugate acid of F minus? And we'll throw this one in here too, the acetate anion. So, the fluoride anion. All you got to do to figure out the conjugate acid of something is take what it is already and add a proton to it. Okay, so we got F minus here. If we add H plus, right? It goes to H. Okay, notice that the plus and the minus cancel each other out so there's no charge here. Okay, and then you just put the H and the F together. Okay, so let's do the same thing for this. Right? We want to find the conjugate acid of the acetate anion. So, all we want to do is add H plus, right? For our proton. And when we do that, the plus cancels the minus out, right? And we get CH3C00H. So, this is the base. This is the conjugate acid. This is the base. This is the conjugate acid. Okay? Okay.
