Which anion could be used to selectively remove silver ions?

    The question is, which anion could be used to selectively remove silver ions from solution? The options are Cl, SO4, or CO3.

    All 3 of them form precipitates, but is there any that is better than the others?

    Do you know what other cations are present in the solution? If you're trying to selectively precipitate silver ions, it is important that the salt you add does not also precipitate other ions.

    Another thing to consider: for which of the three potential precipitates molar concentration of Ag+ in the saturated solution is the lowest?

    Check your solubility rules and that should guide you. Transition metals are generally insoluble unless paired with another anion which is soluble.

    And what are "soluble" anions?
