Options:
- a) If a substance loses hydrogen during reaction, it is reduced.
- b) If a substance loses oxygen during reaction, it is reduced.
- c) If a substance gains hydrogen during reaction, it is reduced.
- d) If a substance gains oxygen during reaction, it is oxidised.
- a) If a substance loses hydrogen during reaction, it is reduced.
- b) If a substance loses oxygen during reaction, it is reduced.
- c) If a substance gains hydrogen during reaction, it is reduced.
- d) If a substance gains oxygen during reaction, it is oxidised.
correct answer : a)
Explanation:
Oxidation is gain of oxygen or loss of hydrogen. Reduction is loss of oxygen or gain of hydrogen. Statement (a) says if a substance loses hydrogen it is reduced, which is incorrect (it is oxidised).
