Which change in oxidation number indicates oxidation? A) Ito +2 C +2 to -3 B) Ito -2 D) +3 to +2
tatuchka [14]

As there is the increase in Oxidation number from +1 to +2. Hence, the correct Option (A) i.e, 1 to +2,

<h3>What is Oxidation ?</h3>

Oxidation doesn't necessarily have anything to do with oxygen.

  • Oxidation occurs when an atom, molecule, or ion loses one or more electrons in a chemical reaction.
  • When oxidation occurs, the oxidation state or oxidation number of the chemical species increases.
  • Oxidation doesn't necessarily involve oxygen! Originally, the term was used when oxygen caused electron loss in a reaction.

Hence, Option (A) indicates the oxidation as there is the increase in Oxidation number from +1 to +2.
