Question

Fe2O3----> Fe ----->FeCl3----->Fe(OH)3-----> Fe2(SO4)3

Answer 1

\(Fe_2O_3+3H_2\underrightarrow{t^o}2Fe+3H_2O\)

\(2Fe+3Cl_2\underrightarrow{t^o}2FeCl_3\)

\(FeCl_3+3NaOH\rightarrow Fe\left(OH\right)_3\downarrow+3NaCl\)

\(2Fe\left(OH\right)_3+3H_2SO_4\rightarrow Fe_2\left(SO_4\right)_3+6H_2O\)
