Answers

Use the given molar solubilities in pure water to calculate Ksp for
each compound.
a. BaCrO4; molar solubility = 1.08 * 10-5 M
b. Ag2SO3; molar solubility = 1.55 * 10-5 M
c. Pd(SCN)2; molar solubility = 2.22 * 10-8 M

So now we work on problem eighty six from chapter seventeen. So here we're calculating the Mueller Sally ability based on the cast piece SAI Ability product constant. And for the first one were given a generic equation X So we can write the equation for the dissolution of this compound in water. It couldn't be him to plus or m plus or and three pluses. Long as thie ex has the same charge. So it doesn't matter based on this for the story geometry, it's a one to one ratio. So for both of them will be adding s and we have equilibrium. Concentrations of s so caspi is equal to these two concentrations multiplied by each other equilibrium concentrations which is equal to its given in the problem one point two seven times ten to the minus thirty six, which is equal to X squared. So when we take the square root of both sides, we get s is equal to one point one three times ten to the minus eighteen, which is our answer for a So if we move on to party now, were given an actual molecular formula for silver Crow made silver to see R O for solid and could potentially dissolve the form two silver plus ions and one chrome it. So we draw our eyes table Disregard the solid new initial concentrations we had to s because of this co efficient. We add us to S s So we need to draw our equation here. So K s P is equal to silver concentration squared because of the coefficient in chrome eight multiplied bankrupt me and this is equal to from table seventeen point to one point one two times ten to the minus twelve table seventeen point to which is equal to we have to s squared times s so this is equal to four s Cute. If we square inside the princess we get for a squared times s is equal to for us Cute. So to solve here we need to multiply. We need to divide both sides here by four and take the cube root. And when we do this to both sides gets six point five for times ten to the minus five. So for part three for party scene, we're given calcium hydroxide No which can dissolve to form calcium to bless close to hard drugs right in our hands When we draw the ice table we have a change of s for calcium and two es for hydroxide And we'LL have a cool librium Concentrations of s and to us So we drunk A s P is equal to a four point six eight times ten to the minus six from the table table seventeen point two And as I mentioned on the last page, we're due for as Cube because we have to s squared kinds of s And so we divide both sides by four to cancel And then we have to take the cue route as well of everything. And when we do that, we get asked is equal to one point zero five times ten the minus two Mueller which should be the concentration for all of our We should be the unit for all of our answers

So now we'LL work on, uh, her seventeen problem ninety four. So here were given a generic compound MX and were asked to calculate the Mueller ah sai ability of the compound in different environments. So first it asks us about impure water so it will dissolve into its constituents. So impure water, there's no initial concentration of either ion. We add s and we have equilibrium. Concentrations of s. We have chaos p equal to what's given as one point two seven times ten to the minus thirty six. Is he going to s squared? If we take the square root of both sides, get s is equal to one point one three times ten to the minus eighteen. So that is without any any other ANA company in the water. Now the question is, what happens if we're working in an environment with one of the other ions? So in the case for Part B, we're working in a saw, an environment that has this metal chloride. Let's say so. Let's go ahead and draw out the reaction again and our ice. So this time we're starting with zero point two five a metal plus no x minus and we're adding s adding an s and we have equally being of zero point two five plus es and s. So we go on, go ahead and solve chaos. P is equal to one point two seven times ten to the minus thirty six and then we have is equal to zero point two five wass s times s. Now, since we're working with a very small chaos P, we can safely say that we can say yes is small, like we said excess small when we were doing essence bases. And we can say that this is just equal to zero point two five s. So when we divide both sides by zero point two five, we get five point zero eight times ten to the minus thirty six. We can see that this is dramatically smaller. Then the value we got here times ten to the minus eighteen. So this indicates that the common ion effect as well is a large presence here. So in our last situation, we have some of the excess minus an eye on already present. So he has your point two zero Mueller of X minus the adas. And once again, we draw K S P equal to one point two seven times ten to the minus thirty six is equal to zero point two zero s s times as we eliminate that and we say it's equal to zero point two zero s. And once again we divide both sides by I zero point zero and we get s is equal to six point three five times ten to the minus three six again, drastically smaller than parquet, slightly larger than part C because our initial concentration here is slightly lower.

So if this problem were given Moller soul ability values for three com boned and we'LL have to find the case Be velo for those compounds. So first we need to know the relation between case B and the mother cell ability off a component. So if a compound every form of love am x em then ah, the KSB off that compound willbe equal to aim is to depart AM Where is the mother cell ability? And I am so coming from here Times in is to the party end are again answer coming from here And this is the Mueller celebrity on the lamp on. And if we just rearrange it will have him to the bar m into the bar in is to the bar in plus and some. Now, if you just no, their formal of the component. We know the virus off him and and, as you know, here, the smaller celebrate of the compound we can easily know the value ofthe case before his compound here by applying this formula. So for the first one we have on the compound formulas, M X, that means, um, the value of boot him, and in here are one. So we'LL have, um the expressionist case being well because toe is square now the value ofthe Siri's three point two seven times Still woman is eleven And if we just put the square we'Ll find a case people for this which is one point all seven times go minus twenty one Now for the second one, we have the com bone bb if two. That means, um the aim is developed in here is one and the well off in his too. So our case b will be called to I came to the bar and means want to the poor one And so do the birds too. That means two square and extreme or implicit means is truly worth three. And here we have the Mueller celebrity Hello are the heirs villas five point six three times still over minus three So you just like the value here for s we'LL have the case people whom for this compound has seven point one for time Sturdier minus seven And then for the last one We have mgf too for which you have the value ofthe him again as one and well off in as two and similarly will have the same expression. Kids will be too Square s cube. And if we just so for this one, we have and is Velu off or the molars celebrity of hello as two point six five times ten to the minus For him it was put that value for this is we'll have the case People whom for m j F two as seven point four four times tend to the bar minus eleven. So this is the case the vellum for M j f too.

So now we'LL work on problem twenty from chapter seventeen. So the problem here is what is Mueller Sally ability. And how can you get Melissa liability from K S. P. So Mueller sally ability is a a measure of the SAI ability of the compound in moles per leader. Okay, so to get to Mueller soluble ity from K S P, we have tio make a nice table. So just teo be able to show this. Um, clearly, I'll use an example so we can have silver chloride which in solution willbe an equilibrium with silver plus and seal minus. So here the we don't take into account the solid and then we initially have none of the ions and solution, and then we add s for an equilibrium of Tess. And so once we have this, So we're assuming we know K s P because that's what the problem ask us. So if we have, if we know Caspian weakens that caspi equal to s squared, so products over react insp. But in this case, we're not taking into account the reactant and so s our moller soluble ity is equal to the square root of K s p. This expression here does not hold true for every system. It just holds true in this case because of the one to one ratio here with our ions. But this is the strategy that we would used to find it in any situation.
