प्रश्न

Assign oxidation number atom in the following species.

H3BO3

संख्यात्मक

उत्तर

H3BO3

Oxidation number of H = +1

Oxidation number of O = –2

H3BO3 is a neutral molecule.

∴ Sum of the oxidation numbers of all atoms = 0

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

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

∴ Oxidation number of B + 3 – 6 = 0

∴ Oxidation number of B in H3BO3 = +3
