The following very strong acids are formed by the reactions indicated: $$ \mathrm{HF}+\mathrm{SbF}_{5} \longrightarrow \mathrm{HSb} \mathrm{F}_{6} $$ (called "super acid," hexafluoroantimonic acid) $$ \mathrm{HF}+\mathrm{BF}_{3} \longrightarrow \mathrm{HBF}_{4} $$ (tetrafluoroboric acid) (a) Identify the Lewis acids and bases. (b) To which atom is the H atom bonded in each acid?

So we're going to identify for these acids which part of the acid is actually taking part in the net ionic equation. When we write them for strong acids, the ionized completely. So the reacting species or the thing taking part in our net ionic equation is simply the H plus the an iron will be a spectator ion for weak acids because they don't ionized very much. They stay together. We write the entire acid. Okay, we don't want to break it into its ions because that's not really indicative of what's happening in solution. So the first thing we're gonna want to do is go ahead and identify these as strong and weak acids. Okay, so as we go down the list, okay, type of Cloris acid is a weak acid. This is a weak acid. Acetic acid is a weak acid. HBR though is one of our strong acids, there's only eight of them. And then again, this is a weak acid. So if we were to write this as part of a net ionic equation for our weak acids are reacting species is the entire acid. We just write it because it's not breaking up in solution, It's staying together. We want to make sure we're representing it as it really is strong acid. However, we're just going to write a check plus and ignore the br minus. So that's how you write your reacting species.

So, uh, we have a couple of reactions of Hydrofluoric acid H f in each reaction. It is an unshared pair of electrons on the flooring bonding to the non flooring. Adam, Uh, the end, the intimate e SB here and the moron as the boron there. Sorry s O. This is the Lewis base in each case. And, um and of course, then this is Lewis acid in this reaction. And this is Lewis acid, as as boron compounds typically are because they have unsure. They have incomplete oc tepes. And they're looking for an electron pair from something else. Something else to be the electron pair donor. Ah, And as to which Adam the hydrogen is bonded to in the acid, it stays bonded to the flooring. Ah, but becomes much more acidic since that flooring is now bonded to another Adam

In this video, we're going to be talking about some examples of weak and strong acids and bases. So our first example is going to be hypo glorious acid. So hypo glorious acid has this formula and hyper chorus acid is a weak acid. So by definition a weak acid does not associate 100% when it is in solution. The ph value is going to be less than seven, but it is not going to be as low as a strong acid. If you compare this two perk Lorik acid, you can see that, that this acid, the hipaa Cloris acid has less electro negative oxygen atoms in it, so it has less electra negative atoms pulling the electrons away from the hydrogen. When the electro negative atoms pull the electrons away from the hydrogen, it makes the hydrogen easier to lose. So therefore it's easier for this poor cork acid to give up its hydrogen. So that explains why we would have hyper Cloris acid as a weak acid versus the poor clark acid, which is a strong acid. Now, let's look at another example. Another example is going to be formic acid, former gas. It is also a weak acid. It does not associate 100% former gas. It is produced by ants. So you wouldn't really expect it to be strong because usually when you touch an ant, you never really experience anything too dangerous when interacting with them. So that's the way to remember that this is a weak acid formic acid. So again, ph will be less than seven but it won't be as low as the ph of a strong acid. Now, let's talk about another example. This is a very common example. This is acetic acid, acetic acid is found in vinegar and you will work with this acid in the lab quite often, it is weak and relatively safe to work with. Yeah, hydro veronica acid, on the other hand, is a strong acid. The reason is because hydro brahmanic acid has hydrogen paired with one of the group seven and ions where the hell agents when we have hydrogen paired with the group seven and ions, they're always going to end up being strong acids. With the exception of HF, which is actually a weak acid. The last example is sulfurous acid, which has this chemical formula. This is also a weak acid. So two understand why this is a weak acid. We can compare the formula of sulfurous acid to sulfuric acid and we see that the sulfurous acid has less of the electro negative oxygen atoms in its formula. So again there are less electro negative atoms pulling the electrons away from the hydrogen. And this makes the hydrogen harder to be lost from this molecule. So that will weaken the strength of the acid. And that's why that's a weak acid.

So we're trying to see what products we continue from using less. Wrote Tuck. Try a late with all the free agents, and it gives us from a video. So this will be a quite long video with a lot of this is gonna be me trying to drive peace compounds. So the first thing we know we didn't with what everybody might was. Well, Charlie so now this first, we're extremely it with someone should get actually, the registry action. So it's this, except for me, so be Archie. And we put the top and then at the bottom, this wannabe in CH two c l two position of physical reactions taking place, and I'm going this reaction of you and it's clean ways of the previous line. Just why not a room, guys. Well, the next one I'll work on actually wearing the smallest within two hours to get online. That's gonna be a problem with this problem. So live long compounds, and then they both down. So this see here, you know, make them to make the smaller guys. So I'm sorry. So this does Look, that's the 1st £1 guys. Now, the 2nd 1 had to save space on first reverse his age, but I think it's more had quite a few times in the prop guys and the Knicks. We know this will, Charlie. So I was gonna be there. Something's not right now. This procedure now and then that gives us an hour have all states to now is not quite today. But there's the solution to that problem. Um can fit CEO here to using something my dark side and water connected that maybe I'm gonna try to see her to us. So when they were using 17 March arts, okay. And then I'm going to You're afraid for more time because we keep down. We'll see. Okay. And actually hurting you're hurting are more refresh. And then finally could do damn it in there. We want say, guys, I'm sorry. That was a really
