Question 24A group of students were tasked to perform the metal coupling of iron nail similar to Experiment 3: Corrosion of Metals. They weregiven two metals, metal Q and metal J, to couple to iron nail. They prepared an agar medium with KgFe(CN)6 and phenolphthalein.Their professor informed them that metal Q forms an orange color while metal J forms maroon color when oxidized. Theirprofessors also gave them the reduction half-reactions for the corresponding metal ions including the reduction of Fe2*.12* + 2e -Fe2* + 2e-- FeE° = - 1.66 vE° = - 0.44 vQ2- + 2e-QO2 + 2H20 + 4e- 40HWhich is the reduction process that occured for Fe nail coupled with metal J?E° = - 0.25 vE° = + 0.40 vAQ2* + 2e - -QB 02 + 2H20 + 4e- 40HĮ 2* + 2e: -)Fe 2* + 2e - Fe1.

The reactions given are, Given: Reduction process of Fe and its coupled with the metal J.

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.
