5. What are the solubility rules for common ionic compounds in water? 6. Balance these reactions and classify it: a. The combustion of decane (C H forms water and c...

On the basis of the general solubility rules given in Table $6-1$ predict which of the following substances are likely to be soluble in water. a. aluminum nitrate b. magnesium chloride c. rubidium sulfate d. nickel(II) hydroxide e. lead(II) sulfide f. magnesium hydroxide g. iron(III) phosphate

All right. So for this question, we're again talking about some solid ability guidelines um with our four different ionic compounds that we're going to be using as examples A. B, C. And D. Throughout our little skeleton here. And we'll start with A which is going to be our and H. For harmonium. NH 42 The two is just there to balance out the charge with the S. 04 are sulfate and in this case both the sulfate sulfates are generally soluble and almost everything connected to pneumonia ion is also going to be soluble. So both of these indicates a liability. That means this is definitely a soluble ionic compound. Next we have our barium B. A. Carbonate, P A. C. 03 Now this is a little bit unique um because carbonates are sometimes soluble but because barium is a group three element, barium isn't group three on the periodic table. This actually becomes insoluble due to the barium. So this is going to be insoluble. The fourth example we have here is our PB lead nitrate and oh three. Now in general, lead is insoluble, but nitrates are very soluble. Um And if you look at our sustainability guidelines ah there is no exception for nitrates um to be insoluble when combined with the lead, that means that this is actually going to be a soluble ionic compound because of the nitrate. And finally we have kind of another unique case actually. Our calcium hydroxide, C. A. Oh h hydroxide is pretty unique because it can lead to some slightly soluble compounds which is exactly the case here because our hydroxide is kind of soluble and our calcium is soluble. But because of the hydroxide here, I forgot to add that too, because the hydroxide, this is actually a slightly soluble compound. So well draw, kind of a half check it's slightly soluble. Um Now we're gonna go through a little bit of what our question asks which is to actually write out the reactions with water. So we'll add our water for the soluble compounds here these are both going to be solid obviously because they need to dissolve in the water. Most ionic compounds are going to be solid anyway. But especially when we're talking about scalability guidelines, those ionic compounds are going to be solid because you need to show it's the premise of the problem that you need to show that they're going to dissolve in the water or they're not. So we have our liquid water combined with our I had it compounds and our little reaction arrow. And because these are both soluble they will fully disassociate, meaning they will split up into their ions. We'll have our N. H. Four and 84 Ammonium plus ion plus are S. 04 is actually Sforza to minus. Um So as you see, we have our little to hear that means we're going to need to ammonium ions to balance out the charge plus our nice little water that the I answer dissolved in. So this is going to end up being liquid water and these are both going to end up being Aquarius because they fully dissolve in the water. So these are both Aquarius uh pretty much the exact same thing here. We're gonna split up our ions. PB PB can have different charges like most of the transition metals. Um But in this case we'll use our two plus because there's too nitrates here and we'll do our two and three minus that way the charges are balanced again, these are both going to be Aquarius AQ and a Q. Unlike any of the insoluble ones, which would end up with solids and the mix of the water H 20 liquid water. All right, so we went over our sustainability guidelines. Did some examples, talked a little bit about some unique, unique exceptions, and finished off with our reactions.

Okay. So for the first one, you have NH four hole twice as so. four. So this is soluble and the equation will be Energy four hole twice. And so four move from energy food positive plus and so forth through negative two X. Moving on to the next one. Barium carbonate is in Hollywood. See part is lead nitrate in solid lead nitrate, a solid will. So this is BBN- 03 forming sleepy, too positive alliance, Less and all three negative lines and the pot is consumed. It's hydroxide and this is also soluble equation is see which will twice reform See you two positive across list, always negative, of course.

So feel following question, we want to use table 4.1 to figure out some re agents that can interact with the ions that we were given to make a precipitate product. So, for a for the chloride ion, we know this to be following three with easier to read, and we could go ahead. And right now, the net Ionic equations, silver chloride for first got a lead, two plus plus two c l minus. And we see why we need it when we look at our products P B leg in two coins. So next we have our G Mercury to two plus. Then again, we're gonna do the two c l minus. Because we're going to make mercury. I don't says it for a looking at B for the calcium ion and using table 4.1, we find that we can use the following three agents. No, it's a little bit actually see, so we could go ahead and make our net ionic equations. We got calcium, and then we need three calcium here and two of our p 04 group. This has a charge of minus three, and that's because we have three calcium in two of our phosphate. So now we can we want to see and see We're going to be talking about the i r iron three I on which means using our people 4.1 we can use sodium hydroxide, sodium sulfide and a to C 03 So we are using iron three i on which means it is iron the re plus. So first we're gonna do 30 h. Name. We do this, Mary C Iron oxide like this, and we have to f e three plus here, plus three sulfide. This is gonna make iron sulfide. And then lastly, we're gonna have a two here again, F e three plus plus, this is going to give us e to three three. That's fully ballast and worked on with that one so we can go ahead and move on to D About halfway done. Thanks for bearing with me. So this is, um, a sulfate ion that we're talking about this So we're gonna talk about barium chloride lead, and it's very important that we write thes re ages out correctly since they are what we're looking at when we're taking Theo ions and separating them to make our net ionic equations. So we have Miriam two plus with thesis Ole Fate Group my own make barium sulfate And then we have the lead. Let's sulfate. Then we have the calcium in the Sofyan I on to make county muscle feet and we didn't have to balance or anything. You were good to just write it as is. So next we have E and our last is F. Seuss's. We're gonna talk about vour Khoury One eye on. And for that, we would have three re agents again using the table 4.1 chloride and sodium so you can go ahead and start our net. Ionic equations. The's sulfate group of our first Regent listed is gonna be, 04 have she to plus two chlorine ill. And that's because we have h G to C l two. We're looking at these charge and then last but not least, we're going to do the same thing for the iodine I on and we're gonna get h g Jasper Khoury, too. I wish I nine to so last but not least, we're gonna be talking about what's ah, silver ion. So we can use sodium bromide soon Chrome eight and oh, the re p who for? So when we're looking at our net Ionic equations here, we're gonna dio are silver. We know we're gonna need three who have three re agents We're gonna take the bro. Mean I on c r o ra minus and Pete. 04 three miles. So this makes a G three p 04 which means that we need a three here. Here we have a G two, which means that we need This is a to minus and means we needed to hear and then for this when we simply have silver wine and that's it.

How everyone. So today we got a problem from, um, Jeff, the eight reaction in a queer solution under problem number nine. So the question is, are based on the general salute. Beat the rules given in table a free one and wish of these compounds are not so doable in water. So the first thing that you do is to write out a chemical bundler on these thought Because you need to know about which kind of indian or occasion is assault that, um and you conveys on that. And based on the table 8.1, Teoh know whether the start it's a little beady salute. More or not. So we have right out. So the 1st 1 that we have is Eireann hydroxide. I want 300. So we know that there is the hydroxide room in here and based on the table, you know that all the hydroxide is, um solu able except in insoluble. Sorry. Exactly. All route number once which should the after line metal on the periodic table. So it, um, insulin over? Well, step or in a plus, a flood, and I think it on drip one. Okay. Therefore, we can know that the island re had oxide is influentials in water. Okay, so the next one it can see harmony, which we have. The former is the A C O tree. And you see, we have our company grew in here. We have a can see on dust on the second group off the pier, on the table, the four time medals. And we know that off the carbonate saw is insoluble except or the the rip one. Also, they're one nickel. Okay. And therefore we know that can say heartburn a warm a white precipitation in in water and so and also can see company on the cover neighbor, it also salute ball with the Amani and us. So the next one is koban three force be with we have still feel for is so when you define it you see you have a coman metal and appeal or dream, uh, work. So we know that feel for, um, feel phosphate group is insoluble except with the except or off the e. Yeah. Um, yeah. Except for the at the line mental and ammonia and soda for just started. Also in salute in, uh, level is okay. And so finally we have, um we have a room off. Um, so for floor I, which is redan chemical for Miller F e a g CEO. So you analyze it. You see that the fluoride room is so Lubell? Most of the the saw. You, uh, do not. So it Except or metal E uh, silver and the, uh, Lee, which they, uh, PB Yes. Yes. So therefore, you know that, um, you know that the silver chloride and insult Lubell and we'll form our festivity. And so we based on the precipitation reaction in Based on this, the Louisville the Ruin table April 1 that we can decide the flu video Easter. Well, thank you.
