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

Answer»

If both assertion and reasn are true and REASON is the true EXPLANATION of the assertion
If both assertion and reason are true but reason is not the true explanation of the assertion
If assertion is true but reason is false
If both assertion and reason are false

Solution :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
