The oxygen is reduced because it undergoes a partial gain of electrons. The oxygen atom in water has greater electron density near it than they did in the O₂ molecule.
What is Reduction Reaction ?
Reduction is a chemical reactions in which the number of electrons associated with an atom or a group of atoms is increased.
The electrons taken up by the substance reduced are supplied by another substance, which is thereby oxidized.
The hydrogen is oxidized because it added oxygen to form water.
Conversely the oxygen is reduced because it added hydrogen to form water.
Therefore, The oxygen is reduced because it undergoes a partial gain of electrons. The oxygen atom in water has greater electron density near it than they did in the O₂ molecule.
