Write a balanced ionic equation and net ionic equation for each of the following acid–base reactions:
(a) $2 \mathrm{CsOH}(a q)+\mathrm{H}_{2} \mathrm{SO}_{4}(a q) \longrightarrow \quad$ (b) $\mathrm{Ca}(\mathrm{OH})_{2}(a q)+2 \mathrm{CH}_{3} \mathrm{CO}_{2} \mathrm{H}(a q) \longrightarrow$

So we have Thio fight departments, the energy equation for the foreign reaction and then we're going to enable the 100. You get acid base pair. So first of all, we have a certain natural side reversed. So do you, Um, di hydrogen force feet and we reformer water and also sodium 100 false fate. Okay, so for this case, we were dying. Thio first find out they're dead. Two different way to do that. First off, or we just separate off the irons and then we're going to we move this potato, Ryan second, we're going second way to do it with you. First, identify which I actually go into the ration, and then we're going to only show that I end and then we're going to a biased or chemical reaction. So from here, we can see that we're some natural science, all the ah, heading divorce feet. And, um, as we made Oh, that rescue mate. Oh, that's the sodium. They always as a spectator ions so that you don't do anything, so we can't just simply we move the sodium r i n for this question, And then we would have, um, our patrol sign with Ah, the hydrogen force free, um, irons. And they're going to fall water. And also, if our heart ginger force feet and I and is exactly the, um, the letter ionic equation. So second match. Now, let's do AA chapter Sceviour at the bonds that So I don't think we have to bonds that because everything should be everything should be fathers. Okay, So from here, we can see that you have had your science or your base. The other island would be. That's it. And then, of course, the base you will form a congregate. That's it from, Ah, the truck signs. And then the hydrogen force may well be the country based off the diversion of Osprey Heights. Okay, it's a second question where potassium Hodgins, self aids, and we have a blessing carbonate. And then we have some company and possessing Hodgins Self eight. Okay, I get it from here. Ah, we use that to remove this potato wine again, sodium and also for taxi. So we must remove the potassium and we'll have ah on so fate. And also we have ah carbonate aliens. And that we're going, they're going to We at it will form a selfie, and I am. And then we have a hydrogen carbonate hyeon and thesis ta. Um, they're on the question I have thinking spot on. So we don't have to do anything. Thio finds it. Okay, so the next plane, we can find that this weird. The Hodgins yourself for Sophie were coming and acid ah, company would be a base. So we will form a con Trick you base and also your former congregate acid. Um, so those are the pair?

That's right. A balance formula. Complete non Ionic equation for each of the following. Acid base reactions for a or at the formula equation. Abbreviated F E If h. Cielo four and make me see my truck side. Just a solid and this would produce and g c l 04 to a quiz and H 20 liquid. To balance this to here to here we're right out completely on a conclusion by breaking up all of our equals species. Here is our plead Ionic equation. Now we can write our Net Ionic equation. Well, um, it the spectator to Hello four minus, which appears on both sides, and our Net Ionic equation will be to H plus Yeah, Q H two forms Energy to plus and to H two of them. There's a Net Ionic equation for be the formula equation between H. C N and sodium hydroxide, anyway. H This would produce sodium sign it and a CNN in h 20 And this is balanced as it is. We can write our complete ionic equation on this would be a church since H C. H Plus CN minus any plus, which minus us C minus h 20 and their Net Ionic equation. Let's omit Spectators and a pluses of Spectators. CN minus is a spectator and Arnett, I like equation is h plus at O H minus to produce h 20 And for see, we have HCL and any Ohh, pretty sodium chloride. I need you to. Oh, and this is a market here. This is our formula equation. Pleading on equation of break apart all of our Equus species and omitting Spectators from the complete Ionic equation and a plus. See how minus our net Ionic equation is each plus coach minus to produce h 20

We have a total of three net Ionic equation corresponding to the equilibrium so three equation can be represented. US. Second equation Will be tart equation can be represented us. There will be three dissociation constant with their three reaction respective, respectively. So okay, a one corresponds to First Association. It would be concentration off product multiplied, divided by the concentration off reactions. The second association going student can be represented us the toad. The association will be your phone negative three. Divide multiplied with it's 30 positive concentration divided by it's You're four to make.

So for this problem, we want to talk about what products are made from these pairs of reactant and also what their balance questions are complete. Ion equations are and that ionic equations are so he at this first question first we want to dio is right out fully balanced equation. And to do so, we have to be able to do what the products are. And since this is an acid base equation, we know that one of the products is gonna be water, and the other is gonna be a combination of the two reactors that we have. So starting this out, we have for our first reacted per cork acid, which is each c l 04 and then we have magnesium hydroxide, which is M g o h subscript two. It's a solid. We find these to react. INTs make magnesium for Corey, he and our water. So when we go to balance this equation, but we want to look at is we want to look at all the different components. So we're looking at magnesium. We have one on a reaction site and one on her products sites. We don't have to worry about that when looking at our Corinne's. We have one on this side. We have to on this side machines. We're going to at least need a two here. So if we look at what that did for those looking auctions first it fix our issue with the chorines. So now we have a auction here in two. Here we have eight auction here, and only one here, which means we needed to hear. And then, lastly, it's one of these lines. Look, let's look at what it did to the hydrogen. Now you've added a another coefficients, we have 400 is on this side. We have to and to on this side, which is four, which means that our this equation is totally balance. So now we can look at the complete Ionic equation, so we're going to break up every reactive and product into their eye on components, if possible. So from our first reacted, we have two hydrogen and to C l 04 minus. That's why we see when they come together, they make a neutral product which is our first reactant per horse acid, four magnesium hydroxide. It cannot be broken up any further. It's a solid. It can't re splint I on. So we just leave it as is pull it our product. Magnesium perk. Or it can be We see magnesium two plus C four minus. And we know that this needs a subscript two plus because of this to here. But then our water Oh, this be a to oh, for whiteness because it is too here, then our to water in the liquid form stays the same because it's in liquid form. So now that we have our complete ionic equation, we can look at our net Ionic equation. So we have to h plus because we see only one on the reactive side and no on the product side. But when we look at to see l +04 minus, we see we have one on this side and a matching on the product side, which means that it doesn't have to be included in the Net Ionic reaction. They are spectator ions that we have our magnesium hydroxide. He farmed magnesium two plus and are to water in the liquid form stays throughout. So now I can move on to our second question, and here we're looking at what happens between hydrogen cyanide and sodium hydroxide. So let's focus on making balanced equation first and finding out what our products are. So hydrogen cyanide and sodium hydroxide come together and we know they're gonna make a at least one water, depending on where switch geometries gonna be when we balance the equation and the other product is going to be sodium cyanide and then our water we put in the phases here just so that we know what we're working with, make our lives a little bit easier going forward all of these air in the quickest form except for our water. So if we look at our sodium is first for balancing, we have one on the product side of one on the reactant side. So that's balance. We have one cyanide, one SIA nights of that spine balanced, and then for auction. We have one. I am one never hydrogen. We have to and to, so we don't have to add in equal efficiency. We can stay with the assumed coefficient of one in front of all these already balanced, which means we can move straight on to our complete ionic equation. So H C N cannot be further broken down into ions. It's just hydrogen cyanide. Relieve that the same. But we do have a sodium ion and be hydroxide and are sodium. Cyanide can split, and as such now that our water, as seen in the last one, stays the same. So we see when looking for our spectator ions. In this complete ionic equation, we could get rid of one sodium and the other sodium. So now we can move on to writing the Net Ionic equation. So we have HC N that wasn't crossed out. Our hydroxide was not crossed out. And for a product side, we still have CN minus and our water. It's a little bit easier to see this. It's an end. So now we can move on to our last question, and we are dealing with ah, hydrochloric acid and sodium hydroxide. So first we're gonna focus on making the balance equation, as we have in the others. So we have hydrochloric acid comes together with sodium hydroxide in the results. You products are in a C L, which is just sodium chloride, which is actually equipment to table sold, and our water may go back and add in our faces. Our water is a liquid again. Our sodium chloride is Equus, sodium hydroxide is Equus, and our hydro cork, I said, is a curious as well. So next justice we've done in the past, we want to split up for the complete Ionic into they're different islands. We have one hydrogen when chlorine sodium. When hydroxide one sodium Want decide. Hey, Corinne, on this side. Then, as we've seen in the past, the water stays. So when we're going to cross out spectator spit spectator ions for this problem, we can go ahead and cross out Horan on both sides and the sodium on both sides. So when we combine these, you see the hydrogen, the hydroxide and water. We know this makes sense because hydrochloric acid and sodium hydroxide is a strong acid in a strong base, respectively. Which means that they fully disassociate into their ions and water, which is what we saw here
