\(FeCl_3+3NaOH\rightarrow Fe\left(OH\right)_{3\downarrow}+3NaCl\)
\(2Fe\left(OH\right)_3+3H_2SO_4\rightarrow Fe_2\left(SO_4\right)_3+3H_2O\)
\(Fe_2\left(SO_4\right)_3+3Ba\left(NO_3\right)_2\rightarrow2Fe\left(NO_3\right)_3+3BaSO_{4\downarrow}\)
\(Fe\left(NO_3\right)_3+Al\rightarrow Al\left(NO_3\right)_3+Fe\)
