To determine the amount of magnetite. Fe3O4, in an impure ore, a 1.5419 g sample is dissolved in concentrated HCl, resulting in a mixture of Fe2+ and Fe3+. After adding HNO3 to oxidize Fe2+ to Fe3+ and diluting with water, Fe3+ is precipitated as Fe(OH)3 using NH3. Filtering, rinsing and igniting the ppt provides 0.8525 g of pure Fe2O3. Calculate % Fe in the sample.

show solutions 1. 10.000 grams of Clay was analyze for Iron content. Its moisture content is 2.00%. The sample was digested with oxidizing acids to convert all Iron into Fe3+. An excess of NH4OH was added and yielded a gelatinous precipitate of Fe(OH)3. The sample was then ignited in a furnace and yielded 0.1212 grams of residue as Fe2O3. Calculate the percentage of Iron. 2. A 0.3000 gram sample contains only KCl and CaCl2. The sample was dissolved in water and yielded 0.5000 grams of AgCl upon addition of excess AgNO3 reagent. Calculate the percentage of KCl and MgCl2.
