Fe2O3+6HCl--->2FeCl3+3H2O
FeCl3+3HNO3---->Fe(NO3)3+3HCl
Fe(NO3)3+ 3NaOH--->Fe(OH)3+3NaNO3
2Fe(OH)3+ 3H2SO4---->Fe2(SO4)3+6H2O
Fe2(SO4)3+3 BaCl2----->2FeCl3+3BaSO4
\(1.\text{Fe2O3 + 6HCl → 3H2O + 2FeCl3}\)
\(2.\text{3AgNO3 + FeCl3 → 3AgCl + Fe(NO3)3}\)
\(3.\text{ 3Ba(OH)2 + 2Fe(NO3)3 → 3Ba(NO3)2 + 2Fe(OH)3 (kt) }\)
\(4.\text{3H2SO4 + 2Fe(OH)3 → Fe2(SO4)3 + 6H2O}\)
