- Draw the flow diagram for a calculation that illustrates how to use a titration to determine the concentration of a solution of HNO3, by reaction with 1.00 g Na2CO3.ochem 21. A sample containing magnetite, Fe;O4, was analyzed by dissolving a 1.5419-g sample in concentrated HCI, giving a mixture of Fe2+ and Fe³+. After adding HNO3 to oxidize any Fe2+ to Fet, 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.
