So to answer this question first we need to know the case. Be fellow for both bury himself and killed himself. So the gas be velo or the celebrity product constant for bury himself Fit is one point all seven times ten to the four minus ten. And the case Poor fellow for Gelles himself, IQ is seven point ten times going to the bar minus five now, um so a lower case be velo means that compound will dissolve Are that comfortably form precipitated at a lower concentration. So here we can see that the case people so far bury himself for is much lower than the case people off calcium surfeit. And that means when really add on appropriate amount off sodium self it which is our agin for the precipitation. I'm the calm bones then Ah, the berry himself. It which has the lowest gsp velo wait form them precipitate first. So, um, being so far away from their precipitate first with the Saudi himself, edit now to find the minimum concentration. Um, why so find a way Minimum constitution ofthe sodium sulfite that will trigger the precipitation. I'm the cat down to find that first you have to find out the expression for the Curie ation cautioned for the bury himself. It so reaction quotient is basically the product off our alliance produced from the compound. So it'll be a beer Good class times s O four two minus. And so the cubillo reaction cautioned when it is equal to the value ofthe case be, that is the time when, when the precipitation off the ion start so and the point at which Q is equal to case be, that is the point when the precipitation will start to begin. So if he just right this recall, that means very being two plus times. A PSA for two minors is equal to the case P Velo, which is one point oh, salmon time stated about minus ten. Now we have to find a consolation of self around from here, and we know the concentration off Barry and my own, which is basically the concentration of the barium self effect. Because one day a man will be post from one very himself to monocle that men's, um, the constitutional bury himself. It will be the concentration off very ion, which is zero point zero one zero and we have to find there's a for two minus ion concentration from this equation here. And if we just solve this, we'LL find this. Hello, Officer for two minors are the concentration officer for two minutes. Has one point one times ten to the minus eight muller. So this is the value off the are the minimum concentration which will trigger the precipitation. So this is the medium concentrations ofthe sodium self. It Natalie created the precipitation. Now we need to know find out the consolation of their remaining remaining get down. That will precipitate first when the other captain begins to precipitate it. So for that, we have to set up the oration, cautioned equation for kills himself. It so for killed himself at it will be called See a two plus time's so for two minus. And now we have to find the And as you know, that when for the precipitation to begin, the value ofthe this reaction cautioned will have to be called with the case. People off killed him self it. So if you write this tree cool, we can right, See it two plus and crimes is a forty to minors. And they called him the case people. Hello, which is capable of calcium sulfate, which is seven point ten times ten to the barn miners fight. And now from here, we can find on the consolation of this cellphone down. Assuming that the concert interrupt the kill Chairman is equal to the concentration of the killed himself, which is which is given as they're open zero to zero. So you can write a zoo before two miners, Kal Toh, on the seven point ten times today were minors five over. They killed him and concentration zero point zero two zero. And from here we can find the value of self at the concentration of sulfur ion which will be a three point five five times into the poor minus three Mueller. So this is the This is the concentration of the sulfur down at which killed himself will start to start. Oh, precipitate. So now we have to find So if we can find the concentration of barrier my own at at the time self, it will have thiss concentration. So that concentration of barrier man will be the concentration of bury himself at are the counselor from the barium ion at Bryant when um gets himself in real startle precipitate. So he figures, too. Again, right? Precipitation, reaction, Griffin cautioned. And narration caution for B s o for as they call to case pure BSO, for when, um, the president will form. And from here, when can right be it two plus times. As for Gu miners, the gas privileges one point all seven times generally poor minus ten. And here we'LL replace the cellphone concentration by thiss concentration, which is the sulfur and concentration at when kills himself. Ready starts to precipitate. So if we just put the self around concentration here is that one trip one five five Time's a gentle depart minus three times ten to the poor miner stand. And from here we can find the barium ion concentration when cell phone has a constitutional thiss and that point barium and we'LL ever concentrate enough um, three point all times ten to the power miners eight Mueller That means when self around will have this concentration which is basically the concentration at which kills him self. It will start to, um form the precipitate and that concentration barium and will have this concentration. So that means this is the concentration of the Barry, um, I own are the cat I own, which will basically that first at the plant when on the other, um, compound or other get on with start oh, precipitate.
