HELP PLEASE i'm so stuck.

. The reaction below competes with the formation of the FeSCN2+ complex
Fe3+(aq) + 4Cl-(aq)↔ FeCl-4(aq)
Yellow Colorless
Explain what would happen to the color of a dilute solution containing FeCl-4 if

A. You added a solution containing silver ion, Ag+ (silver ion reacts with chloride ion in solution to form the precipitate AgCl.)
FeCl-4(aq) + Ag+
Colorless
Ag+(aq) + Cl−(aq) → AgCl(s) + Fe(aq)
white precipitate

B. You added a solution of sodium chloride, NaCl.
FeCl-4(aq) + NaCl



C. You added concentrated HCl.
FeCl-4(aq) + HCl



D. You added concentrated H3PO4
FeCl-4(aq) + H3PO4
