उत्तर

HNO3

Oxidation number of H = +1

Oxidation number of O = −2

HNO3 is a neutral molecule.

∴ Sum of the oxidation numbers of all atoms of HNO3 = 0

∴ (Oxidation number of H) + (Oxidation number of N) + 3 × (Oxidation number of O) = 0

∴ (+1) + (Oxidation number of N) + 3 × (–2) = 0

∴ Oxidation number of N + 1 – 6 = 0

∴ Oxidation number of N in HNO3 = +5
