Question

Oxidation of nitrites in presence of potassium permanganate results in formation of:

Answer 1

• The loss of electrons during a reaction by a molecule, atom, or ion is known as Oxidation.
• The Oxidation number of the molecule, atom, or ion increases by Oxidation.
• Oxidation of nitrate in the presence of Potassium permanganate(${\mathrm{KMnO}}_4$) leads to the formation of nitrates(${\mathrm{NO}}_3^{-}$).
• As Potassium permanganate is a good oxidant, it increases the oxidation number of Nitrogen($\mathrm{N}$) from nitrite -3 to nitrate-5.

Therefore, oxidation of nitrites(${\mathrm{NO}}^{2{-}^{}}$) in presence of potassium permanganate(${\mathrm{KMnO}}_4$) results in the formation of nitrates(${\mathrm{NO}}_3^{-}$).
