Zinc reacts with Iron (III) Chloride yielding Zinc Chloride plus Iron precipitate.I dont know what the formula for iron precipitate is.The rest is:Zn+FeCl3----gt;ZnCl2+Iron Precipitate
Iron precipitate can have a number of formulas. It would be any salt of iron that is insoluble in water. If you're looking at a chemical equation, it should have a negative ion formed somehow that would react with the iron. Iron can precipitate all by ifself; it doesn't have to form a salt as was described above. In this case, I think the precipitate is simply iron itself (Fe). 3 Zn + 2 FeCl3 --- 3 ZnCl2 + 2 Fe
