So we have a, uh, sulfurous acid solution at 0.1 Moeller and we are given the two k is for the two protons associations. And we've got five choices for what would be true here. Now, uh, that first Proton is not gonna be strong acid. So it is not going to disassociate 2.1. So we're not gonna wind up with, um, Mawr than 0.1. Can't store geometrically wind up with more than 0.1 of the hydrogen sulfide ions. So that one is out. Um, this one, huh? Wonder about that is the hydro Nia, my on 0.1. Moeller. Well, I don't think so, but let's calculated and see if we wrote out the standard equilibrium and made the assumption that X would be small. Then we would wind up with X, which is the Hydro Nehemiah concentration equal to the square root of Casey and the hydro name ion. Concentration would be 0.36 If you did the quadratic formula and actually worked out, you'll find that it's actually 0.30 So yeah, we're not going to get point when Moeller uh hi. Drawing on my own. Ah, and In fact, we're above already 0.13 with the first proton. Looks like about 20 room three now. So we're left with these two choices. Are we going to get another, uh, 0.6 This again? That's 36% association. We calculated that assuming we dropped the minus X on the 360.10 Ah, but we can only do that if we have less than 5%. Association is 36%. So that is not the answer. But let's see why this is theano, sir. Now, when you take account of the first association, it produces again by the quadratic 0.30 of the conjugal base and 0.30 of the hydro Nia, my on. So when we start looking here at the K two equilibrium, those air our initial concentrations and then take the ice table from there and as we have seen before, then once we plug in, uh, we read the K expression from the reaction we plug in the expressions from the Ellen into the K expression well, where X is added or subtracted. It's probably small. We always check that we found here that it wasn't small, but here X is 6.3 times 10 to the minus eight Moeller, and that is the sole fight concentration. And that is the answer to our question. Both the additional age plus as well as the contra get base. Ah, in the second, equilibrium tend to be equal to or do you come out to be equal to the value of the equilibrium constant?
