Oxidation states of the metal in the minerals haematite and magnetite, respectively, are (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 haematite and II, III in magnetite
Answers
Answer:
(d) III in haematite and II, III in magnetite is the correct answer.
Explanation:
Oxidation is loss of electrons.
The oxidation number of an atom is defined as the number of charges it will carry if electrons are completely transferred.
It is also known as oxidation state.
The oxidation state is always represented in Roman numerals.
We have to find oxidation number of minerals hematite and magnetite.
Hematite
It has formula Fe2O3.
It is a common iron oxide.
It is also known as a healing stone.
It's oxidation state is +3.
Magnetite
It has formula Fe3O4.
It is another oxide of iron.
It is naturally occurring mineral.
It is one of the components used for generation of electricity.
It has oxidation state +2 and +3.
(d) III in haematite and II, III in magnetite is the correct answer.
