In some old European churches, the stained-glass windowshave so darkened from corrosion and age that hardly anylight comes through. Microprobe analysis showed that tinycracks anddefects on the glass surface were enriched ininsoluble Mn(III) and Mn(IV) compounds. From AppendixE, suggest a reducing agent and conditions that might successfullyconvert thesecompounds to soluble Mn(II) withoutsimultaneously reducing Fe(III) (which gives the glassits colors) to Fe(II). Take MnO2 as representative of theinsoluble Mn(III) and Mn(IV) compounds.

1. 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.
