Assertion Fe(3)O(4) contains iron atoms ...

Assertion `Fe_(3)O_(4)` contains iron atoms in two different oxidation number
Reason `Fe^(2+)` ions decoloruize `KMnO_(4)` solution

A

If both assertion and reasn are true and reason is the true explanation of the assertion

B

If both assertion and reason are true but reason is not the true explanation of the assertion

C

If assertion is true but reason is false

D

If both assertion and reason are false

Text Solution

Verified by Experts

The correct Answer is:
b
Correct explanation The composition of `Fe_(3)O_(4)` is `FeOFe_(2)O_(3)` having iron in +2 and +3 oxidation states respeectively `Fe^(2+)` ion present in FeO being a reducing agent decolourise `KMnO_(4)` solution
