Answer 1

Answer #1

Gain of oxygen is called oxidation and loss of oxygen is called reduction

Gain of hydrogen is called reduction and loss of hydrogen is called oxidation

Gain of electrons is called reduction and loss of electrons is called oxidation

Using above three definitions of oxidation-reduction reaction------->

Cu is reduced (as Cu²⁺ gets converted to Cu⁺ which is gain of electrons)

C is oxidized as gain of oxygen

O is reduced as gain of hydrogen

N is oxidized (as N loses electrons)
