Standard silver nitrate solutions are used in the analysis of samples containing chloride ion. How many grams of silver nitrate are needed to prepare $250 . \mathrm{mL}$ of a 0.100 $\mathrm{M} \mathrm{AgNO}_{3}$ solution?

Question Number five is a molar ity calculation that instead of solving for more clarity this time, we're going to solve for the moles of solute silver nitrate in a 55.7 mL solution of silver nitrate at a 0.204 Mueller concentration, we use the mole Arat e equation. Polarity is equal to moles of solute divided by leaders of solution. We know the polarity 0.204 Mueller. We'll set that equal to the molds of the salute that we have been asked to calculate and then divide that by the leaders of solution which we don't know. But we do know the mill leaders at 55.7. If we divide that by 1000 we will then have leaders in our denominator. We rearrange this equation to solve formal salute mold silver nitrate and we get 0.204 multiplied by 55.7, divided by 1000 gives us 0.114 Moles of the salute silver nitrate

That's his question. 56 on chapter 22. We have this conference. You're reacting with silver nitrate, and we have one rule that complex. So it's asking how many moles for this over chloride. So we're gonna part the reaction, and it's gonna react on a switch quarters with each other. Okay, So if we have one mole, uh, the first Coble complex, it's taught me when I won't have one goal of the silver chloride reacting with each other. So for this, that's gonna be one more.

In this problem, we need 100 milliliters. Ah, 1000.75 Miller silver nitrate. But we only have 60 milliliters of 600.5 Mueller silver nitrate available. We add 50 milliliters of the available solution into a flask at a certain massive silver nitrate and then dilute the solution to 100 milliliters were asked to find the massive silver in a tree that must be added to our solution. Our first technical solution is to find out the amount of moles of silver nitrate that we need so we can take the polarity of our desired solution and solve for unknown number of moles. And we want 100 milliliters of this solution so we can do a little unit conversion here in the denominator. And when we solve for X, we find that we need 0.75 moles of silver nitrate. Next, we can find the moles that we have available by taking the polarity of the solution that we actually have and solving for the amount of unknown moles in that solution. So we're told that we pipette 50 milliliters. So that's our solution, William. And again, we need to do our unit conversion to get it toe leaders. And when we saw we find that we have 00 to 5 moles of silver nitrate that's available to us. So when we subtract the amount of moles that we actually have available of our silver nitrate from the amount of moles that we need of silver nitrate, we find that we still need to add 0.5 moles of silver nitrate toe our solution. We can determine what this quantity is Ingram's by multiplying by the molar mass of silver nitrate, and this is equal 2.85 grams. So this is the mass that should be added to our solution that we have available.

All right. So, um, we in this video, we give in our solution one model of this complex, one more of these complexes to react with the excess saliva on it. Uh, first you have Silver Matrix. Okay, that's that is to read the one more off. This compound is a complex. I am okay. Is, uh, match mine are for, And you have to. Floridians. It is a complex. And then how about you? So, first off, we need to understand that we need to understand that only chloride ions presence in the immunizations fear, right, uh, will be precipitated. Sort of. Missed glory in present, in cognition coordination will not be respected him. Only the zone that is outside the complex will be precipitated from the solution by silver metrics. That means we're going to form on the company on a silver chloride right from So wait til Tremaine. How many moles? Medium. I mean, the Montel Civil, credited to be precipitated from the solution, comes off moles. So that means going to write a chemical balance can collection a balanced chemical equation and uncle. Yet at this compound and which name we have the for the living that took him then is a complex Yeah, and current. So area is in silver silver metrics. So we're going to get this solution is a complex here, which is, uh, boots, then toe get initial component. His main ISS for chlorine is chlorine. But but then we're going to get this. This this clerk learning market has been too reactive. Super. So it's going to be precipitated out of the solution as a silver courage. Let me swim toe gets connected ions here morning to this complex servant. It's naked. I am here. Yeah, Plas this silver chloride. So there's a question is balanced as it is because of one model is Kareen ear? One more, one more silver. Nate Silver on Monday off silver. Most of this is one off netted, so there's a question is balanced, and that means we have one more road block. Florida's a za product, a sophisticated, so we're goingto have precipitated toe a moral off amount off silver cradle to be precipitated, and most is one
