function of SnCl2 is that it acts as a reducing agent to reduce FeCl3 to FeCl2 and function of HgCl2 is to oxidize SnCl2 to SnCl4. total iron is determined after reducing ferric iron to ferrous state.
A white precipitate of mercury(I) chloride is formed when a small amount of tin chloride SnCl2 is put into a solution of mercury(II) chloride (HgCl2); adding more SnCl2 turns this precipitate black as metallic mercury is formed.
Due to its molecular geometry, which is bent, SnCl2 is POLAR!
