oxidation state of Fe in FeCl3 is +3. Cl has oxidation number -1 in this case Fe share 3 electrons with Cl so its oxidation state is +3.
Since Fe is a transition metal, the equation varies. If Fe has the oxidation state of +2: Fe + Cl2 -> FeCl2 If Fe has the oxidation state of +3: 2 Fe + 3 Cl2 -> 2 FeCl3
Fe = +3 oxidation state Cl = -1 oxidation state
It contains only two elements. Fe shows +3 number. Chlorine shows -1 as the oxidation number.
The oxidation state of Fe in FeBr2 is +2. The oxidation state of Fe in FeBr3 is +3.
FeCl3 + KOH ------------> Fe(OH)3 + KCl
Since Fe is a transition metal, the equation varies. If Fe has the oxidation state of +2: Fe + Cl2 -> FeCl2 If Fe has the oxidation state of +3: 2 Fe + 3 Cl2 -> 2 FeCl3
Fe = +3 oxidation state Cl = -1 oxidation state
It contains only two elements. Fe shows +3 number. Chlorine shows -1 as the oxidation number.
+2 oxidation state
The oxidation state of Fe in FeBr2 is +2. The oxidation state of Fe in FeBr3 is +3.
FeCl3 + KOH ------------> Fe(OH)3 + KCl
The first Fe represents an iron atom in the 0 oxidation state while the Fe in Fe2O3 represents iron ion in the +2 oxidation state
+2
This compound is not possible, but if it had been, the oxygen should have oxidation state of -4
FeCl3 + NaOH -----------> Fe(OH)3 + 3NaCl
It is called a ferrous compound or a Fe(II) compound.
Assuming double displacement. FeCl3 + 3NaNO2 --> Fe(NO2)3 + 3NaCl
