Solution
The correct option is A 1 mole of AgCl (white precipitate) The complex of FeCl3.H2O in water can be represented as [Fe(H2O)4Cl2]Cl.2H2O. It contains one chlorine in the ionization sphere. It will react with 1 mole of silver nitrate to give one mole of silver chloride which is a white precipitate.
