How many moles of `FeSO_(4)` oxidized separately by one mole of `KMnO_(4)` in acid medium?

Options

A. Five moles
B. Four moles.
C. Seven moles.
D. Three moles

Answer

A

Explanation

`{:(Fe^(2+)toFe^(3+)+e),(Mn^(7)+5etoMn^(2+)),(overset("...........................................................................................")("Thus," 5Fe^(2+)+Mn^(7+)toFe^(3+)+Mn^(2+))):}`
or five moles of `FeSO_(4)` are oxidized by one mole of `KMnO_(4)`.
