To add more ions, but not get any precipitate?

[angela107]

TL;DR Summary

I'm given an equilibrium, what can I do if I wanted to add more silver ions and not get more precipitate?

Here's an image of the equilibrium

I'm not sure how that's possible, but I'm thinking maybe I could remove Cl- ion so that the Ag+ ions don't have much to combine with.

Not sure what you really mean. Yes, you are limited by the solubility and you can't add more Ag⁺ than defined by the concentration of Cl^-. Yes, removing Cl^- will allow adding more Ag⁺. But I have a feeling that can be only tangential to what you are really trying to achieve/solve/answer.

You can't just remove ions - no matter how you plan to do that in practice (some details would be helpful). You need to replace them with other ions in order to keep the solution electrically neutral and it makes a difference if you replace Cl^- with I^- or with NO₃^- (for example).

I wasn't told to perform an action that could disrupt the equilibrium, I just need to find a way to add ions by any means necessary as long as I don't produce any precipitate. Removing Cl- ions could do the job...

Does that mean you may also add something else in addition to Ag⁺ (e.g. NH₃)?

Yes it could. But it matters how you do it. How do you plan to remove Cl^- ions?

If I remove the Cl- ions, I would have to replace them with something else, as long as there is no precipitate involved.

Yes, but what would you replace them with and how would you do that in practice? I have no clear picture of what you want to do and why.

You could pass the solution through an anion exchange resin charged with the anion you want to add in place of Cl^-. If it’s nitrate, charge the resin with ammonium nitrate, rinse well and then pass the AgCl solution through and exchange the Cl^- with NO₃^-. Now you have a solution of AgNO₃. You have changed the equilibrium because [Cl^-] is essentially zero.

Add all the Ag⁺ you want to at that point (as the nitrate, of course).

I have no idea why you would want to do this...

This sounds like a homework problem, without the included problem statement...
@angela107 is there a problem statement you could include?
