Question

Assuming complete ionization, same moles of which of the following compounds will require the least amount of Acidified KMnO4 for complete oxidation?

Answer 1

feso4

is the answer  hope ............................

Answer 2

Dear student,
You didn't mention options here, I'll do that first.

# Options should be -
(a) FeSO3
(b) FeSO4
(c) Fe(NO2)2
(d) Fe(COO)2


● Answer -
(b) FeSO4

● Explanation -
For complete oxidation of FeSO4, only 1 electron is involved.
Fe2+ --> Fe3+ + e-

Let's see for other options,
FeSO3 => 2 electrons involved
Fe(NO2)2 => 5 electrons involved
Fe(COO)2 => 3 electrons involved

More the electrons involved, more KMnO4 is needed for oxidation.
As FeSO4 involves least electrons, it will require least amount of KMnO4 for oxidation.






Thanks.
