Question: Oxidation states of the metal in the minerals haematite and magnetite, respectively, are

Options:

A) II, III in haematite and III in magnetite

B) II, III in haematite and II in magnetite

C) II in haematite and II, III in magnetite

D) III in the haematite and II, III in magnetite

Show Answer

Answer:

Correct Answer: D

Solution:

(i) Haematite is $F e_{2} O_{3}$ in which Fe is present in III oxidation state. (ii) Magnetite $(F e_{3} O_{4})$ is an equimolar mixture of $F e O$ and $F e_{2} O_{3}$ . Oxidation state of Fe in FeO is II. Oxidation state of Fe in $F e_{2} O_{3}$ is III.
