Identify the precipitate (if any) that forms when the following solutions are mixed, and write a balanced equation for each reaction. (a) $\mathrm{Ni}\left(\mathrm{NO}_{3}\right)_{2}$ and $\mathrm{NaOH}$, (b) $\mathrm{NaOH}$ and $\mathrm{K}_{2} \mathrm{SO}_{4}$, (c) $\mathrm{Na}_{2} \mathrm{~S}$ and $\mathrm{Cu}\left(\mathrm{CH}_{3} \mathrm{COO}\right)_{2}$.

So the first creation here is sorry, um, as seated, and it's hell so sodium faceted and which is soluble in water. It will be a quiz form it will react to it isthe seal, which you'LL also be a necklace form, and they will react to form sodium chloride, which is also very strongly saloon in water. That means it will also in AC Woz and finally will have sees through suitable age or acidic gas in which is also soluble in water. So as they know that in a chemical reaction precipitated will be formed on ly if there is any solid compound in the correct side. So since there is no solid in the productive side, that means no preceded, it will farm from the creation. Now for the balancing, we have to check out if we have all the well Adam's already kills in both sides are off equal number. First we check the medal, so mater, it's Saudi and we have one sodium on its side that we have ass. It'd wanna sit it on its side. We have chloride want right on this site and finally we have high treason. One had risen on a site that means this is already a balanced equation and no precipitate will form from this relation Now, in the second one Yeah, we have kill H and see you in a tree too. So village it is solid. It is saluting water and then we'LL have copper nitrate which is also salute in water as all nitrous is soluble in water and the product will have gain of three in AC wass And we will have seaways too. So if we look at the solar, the charred will see that without thirteen exceptions all of them hydroxide, sir, usually in soluble in water and Cooper is no exception. That means corporate hydroxide is in soluble in water and that means it will be is solid. And it will be It will be precipitated out from from the solution mixture. And actually, we have it solid, precipitated here and now for balancing the equation. Let's start with our medals here. We have to meddle. We have one one K or one potassium on it's side. And then we look for the copper. We have one cover on its side. Then we have our two nitrous here and we have one night right here. That canary Habito Eric to here. Now we have two night train but now we have to kill Soto. Poor ashamed. That means we need to production and this side also. And again we have added to put a shame That means we have two hydroxide now. And in this side we have also to hydro site. Now if we just Ah, look for all of them on for one more time We have to put a shim here and Oprah shame here we have to hide. You sit here so I just sit here One copper, one copper and then united to imagine So this is our balanced equation for this reaction. And we have one solid, persecuted farmed now in a tar deline We have sodium sulfide and get me himself but yeah, so get me himself. I'd Oh no story himself and Gandhi himself it And in this relation we will have King Sodi himself at which is solidly in water As you know that all alkali metal composers so level and we'll have get me himself fight now. So now again if you look at the celebrity charge will see that normally all sell five Cy Insoluble, Except some exceptions. And get me, um is no exception there. And that means scales hymns Get me. Um, sulfide is not salable our insoluble in water. And they're so it will be a solid form and it will be precipitated out from the solution. That means we have one persecuted here. Get me himself. Fight. And now if we go for the creation balancing, we have to sodium here and we have to study. I'm here. Then we have one getting him one. Get him. We have one self at oneself and finally wants sulfide oneself fight. That means the situation is also already balanced. So this is the balanced equation for this reaction. And get them sulfide is our solid distributed here.

So in this video, we're gonna go over question 126 from Chapter four, which says the following chemical reactions for the following chemical reactions determined the precipitate produced when the two reactors listed below are mixed together indicate none of no precipitate will form. So the first on two reactions were given our strontium nitrate, as are in no 32 and potassium phosphate K threepio for eso. What products could we possibly formed from these two reactant? Well, if we just swap our cat ions and r and my arms of the two products we conform our strong Teoh phosphate. And remember, Sean team is one of our alkaline earth metals, so it has a minus. It has a plus to charge an ionic compounds and phosphate. This poly atomic ion has a minus three charge s o. I'm going to have three of my strontium and two of my phosphate. So that's the formula for shocking possibility. Um, and then my other possible formula other possible product is just potassium nitrate K in a three. Potassium has a plus one charge, and ino three has a minus one charge. Um, so are these soluble insoluble are we going to form a precipitate? Will most phosphate salts except warns that specific cat ions are, um are insoluble. They're they're only slightly soluble, so they will form a solid. So this is going to be solid, strong tea and phosphate and then most nitrate salts and most potassium salts are soluble. So this is going to be a curious. Um So what's our precipitate are precipitate is the strontium phosphate. The next two reactions were given our potassium carbonate que tu sio three and silver nitrate a g n 03 eso. What possible products can reform from this? Let's swap the cat I owns and the anti ons we get. Potassium nitrate, Kono three And then again, since most potassium salts are soluble and most nitrate salts are soluble, potassium nitrate is a Prius. Not going to form a precipitate from potassium nitrate are other possible product is silver carbonate. So a G to on carbonate has a minus two charge, whereas silver always takes a plus. One charged ionic compounds. So the formula is a G to seo three. Um, and then most carbonate carbonate salts are only slightly soluble. The same is the phosphates Where s Oh, this is going to form a solid. Um, So what? Um, what's our precipitator? Precipitate is the silver carbonate are the next two reactions were given our sodium chloride and a C l and potassium nitrate. Kono three. So what products can we form from that? Well, we conform sodium nitrate n a n 03 and we conform. Potassium chloride. K c l, um, so most chloride salts air soluble, except for specific cat ions. And since the task name isn't one of those cat eye on this is going to be a Prius, Um, and then for our sodium nitrate, most nitrates, alter soluble and most sodium salt is soluble. So this is also going to be a Prius. Um, So what's our precipitate? Well, there is no precipitate. We're not forming any solids here. So moving on to our next two reactions were given potassium chloride, Casey L and A. G and 03 silver nitrate, um, so pretty similar to the last one. So the two products we conform our potassium nitrate, Kono three, and then since most potassium Salter soluble and most nitrate salts are soluble, this is going to be soluble it's Equus, and then the other product we conform is silver chloride A G C L. Now most chloride salts are soluble, but there are exceptions. When we have a cat eye on our silver, it's actually insoluble. So we're gonna form solid silver chloride. So the precipitate we're forming a silver fluoride. Finally, the last two reactions were given our iron three chloride AFI seal three and lead to nitrate P B and 032 s. So what are the products that we conform from? These two make Leah's ionic compounds. We just swapped the cat ions in the and ions we can have iron three nitrate, which would be f e n 03 three are iron has a plus three charge on it in this case, and nitrate always has a minus one minus one charge on it. So we need three of those. So that's one of our possible products. Um, and then our other product is lead chloride. PB sealed, too. Um, so are the soluble insoluble. Will our f b you know, 33 are iron three nitrate. Most nitrate salts are soluble s. Oh, this is going to be a curious and then for the leg to chloride rpv seal To most chloride salts are soluble, but in this case, we're going to be insoluble because our cat eye on is lead. And that's an exception to the rule that all chloride salts are soluble. Um, so so PB seals. Who is going to form a solid? Um, so the precipitate is PVC. L two is led to chloride.

In this problem, we are going to write some net ionic equations and to determine if a reaction occurs based on solid ability rules. So first we're looking at this reaction with sodium. I owns pro my lions led irons and nitrate ions in Solution. So looking at our scalability rules, sodium and nitrates are generally soluble, so these will not precipitate. However, lead is generally insoluble, and with bromide ions, they will precipitate together. So are net. Ionic equation will look something like this. Um, these four. Together we'll have our sodium ions that remain in solution. We'll have our nitrate ions that remain in solution, and then we will have our lead bromide precipitate. Since we had a two here, let's just balance this and assuming that it was a sodium bromide next year, this will be our net ionic reaction, and this is our precipitate. For the second solution. We have a magnesium chloride solution and copper sulfate solution mixed together, um, trying to figure out which ones will precipitate. Looking at our scalability rules. Coloreds air. Generally soluble except with heavy metals, sulfates are also generally soluble, except with some group or heavy group. Two elements magnesium is group to, but it is a light group to element, So none of these election precipitated. There will be no reaction here, so no reaction. The Net Ionic equation will just be the same thing. Is this right? All of these will exist, uh, as ions in solution for part C, we have iron nitrate mixed with sodium hydroxide. So again, sodium is generally soluble a group one element. Nitrates are also generally soluble. Hadrt oxides, however, are generally insoluble, and iron will precipitate with the hydroxide. So are net ionic equation. We will have our so diem's that remain in solution. We'll have our nitrates that remain in solution and we will have our I own hydroxide that precipitates from the solution, and that is our net ionic equation.

So in this problem, we are asked Teoh, figure out whether it precipitate will form for each of these reactions. Young here, um, and to read the net ionic reaction for things reaction if it occurs. So first we should look for if something will precipitate from these. So from our scalability rules, we know that sodium is generally soluble and everything as well as the nitrate generally soluble on everything. Lead, however, is not soluble, and it's not soluble with halogen. I am so we'll get a lead bromide precipitate from this. So are net ionic reaction. We'll include. We'll have our lead ion in solution and we'll have our bromide ions in solution. And we'll need to You said that the charges cancel out and these will be P Chris as well. And then we will get our precipitate of lead bromide, and that will be our solid precipitate. And this is our Net Ionic equation For Part B. We're looking at magnesium chloride solution with a copper sulfate solution and from our scalability rules, we know that sulfates are generally soluble, except with some of the heavier Group Two Elements Museum is a group to element, but it's a lighter one. So magnesium and sulfate soluble in solution and chloride ions are generally soluble except with some of the heavy metals. Copper is not a heavy metal, so nothing will precipitate here. They're actually be no reaction because nothing here is insoluble together. So looking at part C, we have iron nitrate solution and a sodium hydroxide solution. So again, sodium generally soluble nitrate, generally soluble hydroxide is generally insoluble. So our iron and hydroxide will precipitate together. So are net. Ionic equation will look like this where we have our iron. Um, and we add our drug sides. These are both Chris and solution and that will yield our iron hydroxide precipitated. That is a net ionic reaction.
