The ${Ag}^{+}$ $"Ag"^+$ ion

Reacting aqueous silver nitrate with a halide ion is the test for halide ions. This is the ionic equation for the reaction:

${Ag}^{+} (aq) + {Cl}^{-} (aq) \to AgCl (s)$ $"Ag"^"+"("aq")+"Cl"^(-)("aq") rarr "AgCl"("s")$

Aqueous solutions of silver nitrate (AgNO3"AgNO"_3) and iron chloride (FeCl3"FeCl"_3) are mixed together. Which ion combines with the chloride ion to form a precipitate?
