  • Answered To determine the amount of magnetite

    To determine the amount of magnetite (Fe3O4) in an impure ore a 1.7832 g sample is dissolved in concentrated HCl giving a mixture of Fe2 and Fe3 . Then Fe2 is oxidized to Fe3 by adding HNO3 and diluting with water. Fe3 is precipitated as Fe (OH)3 by adding NH3. Filtering rinsing and igniting the precipitate provides 0.9179 g of pure Fe2O3.
