Question #e3e9a

Answer 1

It appears to be an oxidation reaction of ferrous oxalate dihydrate by Potassium Permanganate.
Potassium permanganate is a very strong oxidizing agent, oxidizes both the `"Fe"^(2+)` ion and the oxalate ion.

Explanation:

Redox reactions for oxidation of both are shown below:

Oxalate oxidation:
`2"MnO"_4^(-) + 16"H"^+ + 5"C"_2"O"_4^(2-)-> 2"Mn"^(2+) + 8"H"_2"O" + 10"CO"_2`

Iron(II) oxidation:
`"MnO"_4^(-) + 8"H"^+ + 5"Fe"^(2+) -> "Mn"^(2+) + 4"H"_2"O" + 5"Fe"^(3+)`

First the ferrous oxalate dihydrate is dissolved in Sulfuric acid, `"H"_2"SO"_4`
