Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that hydrogen peroxide can reduce ferric ions to ferrous ions?

Yes. Hydrogen peroxide can participate in Fenton-type reactions that involve reducing ferric ions (Fe3+) to ferrous ions (Fe2+) or driving iron redox cycling.

The analysis

The retrieved literature (such as papers 0 and 4) discusses the iron reduction step in Fenton and Fenton-like reactions involving hydrogen peroxide where ferric species are reduced to ferrous ions to sustain catalytic cycles.
