    Answer:

    sodium fluoride

    Explanation:

    When we add sodium fluoride to a solution of a given mixture, we get barium fluoride from Ba, which would be an insoluble salt, and silver fluoride from Ag, which would be a soluble salt. 

    The solubility rule will be used to determine the barium salt that forms as a precipitate and leaves Ag+ salt in the solution.

    From the following equations, we will see that the precipitate is formed in Ba but Ag remains dissolved in the solution.

    Ba(NO_3)_2{(aq)} + 2NaF_{(aq)} \to BaF_{2(s)} +2NaNo_{3(aq)}

    AgNo_{3(aq)} +NaF_{(aq)} \to AgF_{(aq)} + NaNO_{(aq)}
