Explanation / Answer

KI can be a separating agent as it gives yellowish precipitate with Ag+ but does not give any precipitate with Ba2+.

Ag+ + I- = AgI (precipitate)

Na2S can be a separating agent as it gives precipitate with Ag+ but does not give any precipitate with Ba2+

2Ag+ + S2- = Ag2S (precipitate)

K2CO3 can be a separating agent as it gives precipitate with Ba2+ but does not give any precipitate with Ag+.

Ba2+ + CO32- = BaCO3(white precipitate).
