To determine the amount of magnetite, Fe3O4 in an impure ore, a 1.5419 g sample is dissolved in concentrated HCl to obtain a mixture of Fe2 + and Fe3 +. After HNO3 is added to oxidize Fe2 + to Fe3 + and diluted with water, Fe3 + is precipitated as Fe (OH) 3 by adding NH3. 0.8525 g of pure Fe2O3 is obtained by filtering, rinsing and burning the precipitate. Calculate the percentage of Fe3O4% in the sample. (Fe = 55,847g / mol, O = 15,999g / mol)
1. A sample containing magnetite, Fe;O4, was analyzed by dissolving a 1.5419-g sample in
concentrated HCl, giving a mixture of Fe²+ and Fe+. After adding HNO3 to oxidize any Fe2+
to Fe+, the resulting solution was diluted with water and the Fe precipitated as Fe(OH)3
by adding NH3. After filtering and rinsing, the residue was ignited, resulting to 0.8525 g of
pure Fe2O3. Calculate the:
a) % (w/w) Fe
b) % (w/w) Fe;O4 in the sample.
Twenty tablets of an iron food
supplement whose total mass was
22.131 g were crushed and perfectly
mixed. Then 2.998g of the powder
was dissolved in HNO3 and the
solution was heated to convert all the
iron to Fe+3. By addition of NH3 it
was quantitatively precipitated as
Fe(OH)3•H20 which was calcined to
form 0.264g of Fe203. Calculate the
Fe content in each tablet.
