Answer:
Oxygen is reduced while hydrogen is oxidized.
Explanation:
Chemical reaction:
2H₂ + O₂ → 2H₂O
The oxidation state of hydrogen and oxygen in left side is zero while on right side the charge on oxygen is -2 and hydrogen is H₂⁺² . So hydrogen is oxidized and oxygen is reduced.
oxygen is oxidizing agent while hydrogen is reducing agent.
Oxidation:
Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.
Reduction:
Reduction involve the gain of electron and oxidation number is decreased.
Oxidizing agents:
Oxidizing agents oxidize the other elements and itself gets reduced.
Reducing agents:
Reducing agents reduced the other element are it self gets oxidized.
