A mixture of solid chlorides was known to contain some or all of the following cations: Ag ,Al^3+Cr^3+,Ca^2+,and/or Zn^2+ . A student performed the following steps: 1.Water was added to the solid and the mixture was stirred well. After several minutes, some of the solid did not dissolve. The mixture was centrifuged and the supernatant was decanted from the solid (solution A). 2. NH4CI(aq) was added to solution A followed by NH3(aq) until the solution was basic to litmus. A gray-green precipitate was formed. The mixture was centrifuged and the supernatant (solution B) was decanted. The solid dissolved in NaOH(aq) and H2O2(aq) to form a light yellow solution. The solution was heated to dryness to remove the H2O2 and the solid was redissolved in HCI(aq). When ammonia was added to make the solution basic, a light yellow solution formed and no solid precipitated. 3. (NH4)2C204(aq) was added to solution B, and a precipitate formed. The mixture was centrifuged and the supernatant (solution C)…

An ore containing magnetite, Fe3O4, was analyzed by dissolving a 1.5419-g sample in concentrated HCl, giving a mixture of Fe2+ and Fe³+. After adding HNO3 to oxidize any Fe²+ to Fe³+, the resulting solution was diluted with water and the Fe³+ precipitated as Fe(OH)3 by adding NH3. After filtering and rinsing, the residue was ignited, giving 0.8525 g of pure Fe₂O3. Calculate the %w/w Fe3O4 in the sample.
