उत्तर
Concentrated nitric acid is a stronger oxidizing agent due to nascent oxygen which it gives on decomposition.
\[\ce{\underset{\text{Conc.}}{2HNO3} -> H2O + 2NO2 + \underset{\text{nascent oxygen}}{[O]}}\]
\[\ce{\underset{\text{Dilute}}{2HNO3} -> H2O + 2NO + \underset{\text{nascent oxygen}}{3[O]}}\]
