Iron is in +3 oxidation state in Haematite and +2 and +3 states in Magnetite. Haematite: Fe2O3:2x+3× (.-2.)=0 x=3 Magnetite: Fe2O4 [an equimolar mixture of FeO and Fe2O3 ] FeO: x-2=0 x=2 Fe2O3: x=3

Q. Oxidation states of the metal in the minerals haematite and magnetite respectively are

II, III in haematite and II in magnetite

II, III in haematite and III in magnetite

III in haematite and II, III in magnetite

II in haematite and II, III in magnetite

Iron is in +3 oxidation state in Haematite and +2 and +3 states in Magnetite.
Haematite: $F e_{2} O_{3} : 2 x + 3 \times (- 2) = 0$
$x = 3$
Magnetite: $F e_{2} O_{4}$ [an equimolar mixture of FeO and $F e_{2} O_{3}$ ]
$F e O$ : $x - 2 = 0$
$x = 2$
$F e_{2} O_{3}$ : $x = 3$
