Question

to prepare the compound Ferris oxide in the lab​

Answer 1

Answer:

Hydrated ferric oxides are produced by precipitating a ferrous or ferric salt with alkali. In case a ferrous salt is used, the resulting oxide is oxidised by airing or oxidising agents.

2FeSO4+4NaOH=2FeOH2+2Na2SO42FeOH2+O=Fe2O2OH2+H2OFe2SO43+6NaOH=Fe2O2OH2+3Na2SO4+2H2O
