Magnetite is a mineral having the formula Fe3O4 or FeOFe2O3. A 1.1324-g sample of a magnetite ore was dissolved in concentrated HCl to give a solution that contained a mixture of Fe{eq}^{2+} {/eq} and Fe{eq}^{3+} {/eq}. Nitric acid was added and the solution was boiled for a few minutes, which converted all of the iron to Fe{eq}^{3+} {/eq}.
