Choose the strongest acid from each group. a) $\mathrm{HClO}, \mathrm{HBrO}, \mathrm{HIO}$ (b) $\mathrm{HIO}, \mathrm{HIO}_{3}, \mathrm{HIO}_{4}$ c) $\mathrm{HIO}, \mathrm{HBrO}_{2}, \mathrm{HBrO}_{4}$

Empowering the acidic strength of the oxy acids. So what we need to do is consider the basis of the electro negativity and the oxidation today of the halogen atom that we have present. So in this case, all of the oxo acids have very similar molecular formulas where the difference in the halogen atom, so the more electric negative, the halogen atom has drawn the electrons away from the oxygen atom bonded to the hydrogen atom to make the oxo acids stronger. So as chlorine is more electric negative than bromine and iodine, the oxo acid that contains chlorine will be our strongest. So we have Hc L. O. There's our strongest acid. So in the next example, all of the oxo acids have the halogen atom, but we have a different number of oxygen atoms. And so the oxidation state of the halogen atom in each of those will be different. So the more electron negative oxygen atoms are bonded to the halogen. Then this, the oxygen atoms will draw electrons away from the oxygen atom that are bonded to the hydrogen. So therefore in summary, the oxo acid, with the greater number of oxygen atoms bonded to the halogen is stronger than the others. So therefore we have H I owe, for that is the strongest acid. So finally, what we need to do is consider the electro negativity of the halogen atom for each of the acids. So because bromine is more electro negative than iodine, the oxo acid for the bromine containing acid is stronger. So next we need to consider the number of oxygen atoms like we did in the previous example. So the more electro negative oxygen atoms bonded to the halogen atom tend to draw electrons away from the oxygen atom because the halogen can be more electro negative than the oxygen atom. So therefore the oxo acid with the greatest number of oxygen atoms bonded to the halogen atom, is stronger. Here we have HBR 04 that has the highest number of the oxygen atoms, and so therefore this is the strongest acid out of the three.

He had the given coach and s choose this stronger. Is it among the key given pair? In part A. The stronger as it is H. I. O. And in barbie the stronger as it is it i all for is stronger is it? And in parsi the stronger. Yes it is. H. B. Are awful is stronger. Is it? Because it can you get this is the travel and it's going to get based stable due to the greater number of oxygen atom and the negative judge dispersed our the Holman cube and here is conjugate bases travel. Therefore these all are strong acid.

Question is the weakest among those given anything, has a very strength increase as the electronic twin group increase. Okay, so all the halogen compounds are electron veteran group, and a local group are electron realism group that will reach to less than two extremes. So this compound will be recast as a here's the L, b, r and F as the election with drink up. That will increase the strength. The correct option will be seen.

So we have Ah, 1.25 motor off cover acid acid and the PK will find to be 2.87 So we had to find the concentration of hydro Liam concentration off the car acetate Lyon. And also the concentration off cover Ascetic acid. Ah, after decode, IBM may have 1.25 boulder off core asset as it to start with. So first off or ah, I would just, ah, convert this complicated market the formula to be okay, so it just an acid. So I'm going to write, um, of ionization. You re actually question for these assets. So we just refurbished every water and also we have a B minus and also with, um Hi, Joanie. Um, so we're going to sever eyes table. So we re had initially we have 1.25 motor and we don't care about water and high. Julien wears almost zero, and we don't have any a minus. We cost wanting to cover acid eight. So this will be my okay, So the change would be minus. I explained that we have plus X and also there posits over here you could even concentration were 1.5 months Aches and ever bakes headaches. And then for the Caribbean Cobb expression every half hour, actually. Oh, plus times, our of Karak City I and over the asset. So that looks there. We were just going to plucking off eggs. Oh, I mean, the course entry. You got even concentration, Teoh, Um, to the expression. So we're have 1.25 my six. Okay, So, uh, looks stab we're going to solve for X. They were so for us. We will have the Honduran concentration. Ah, veracity, concentration. And also, we can also fire there h a I mean the co acid, the acid at the equilibrium. Okay, how If I am really we're seeing one piece of information will be OK. All right. So I'll but were given PK So, actually PK ihsaa Lev, lock off our, um que So if you want to revert that richer people to find attention minus PK, we're very close to our Okay. All right, so last. Ah, go, Teoh the second page. All right, so we know that the PK your secrets to 2.7. So therefore took out Katie because attention power off. Let if 2.87 Okay, so for these case, we have, ah, 10 to the power night of 2.7. He goes to our ex queer divided by, um, How you need so concentration. 1.25 My six. Okay, so the next step we're going to sell for this court tracked equation. So the level we're half Ah, 1.25 Time our 10 to the power to appoint a seven year, 2.87 not to buy six. And then we have this number minus, um 10 to the power off. 72 times six. And in a very were half x squared. So we just got a call. Smooth flight. Okay, so, um, we really should you question we should be able to find that we have Ah, X square does tend to the power 2.7 aches minus. Turned to power toe to put a seven time 12 porn to five. So you can just so calculated. Teoh saw four X for this quadratic equation. So, uh, so X square would be one, and then we obtained to the power to point Ah, 7 to 47. Always say 26. And then finally, we have minus 10 to the power one through point, ace, Um, seven times our 1.25 So just give me a second. So we should be able to find that takes who Pretty close to see if on zero Ah, four or minus Open zero for two. OK, but you cannot be a my are letting value. The reason is that, um, because their eggs must be positive, you know, to have a high Joni, um, and also a miles to be, um, positive. So extra recalls to Super 04 motor at this concentration essentially goes to the concentration of core acetate. We? Why should we? As a minus and also their concentration off. Hi, Juliam. Okay, So for the concentration off H A or the koru sed acid, it would be close to 1.25 minus 0.4 So we should have because this one when employing one 1.21 motor for, um tickle recipe ass, it
