Formation of water in the reaction of copper oxide and hydrogen proves oxidation of which substance?

Answer and explanation

Correct answer: Hydrogen

The reaction is \(\mathrm{CuO + H_2 \rightarrow Cu + H_2O}\). Hydrogen gains oxygen from copper oxide to form water. As gain of oxygen is oxidation, hydrogen is oxidised. Copper oxide, on the other hand, loses oxygen to form copper and is therefore reduced. Exam tip: In oxygen-based redox questions, the substance that gains oxygen is oxidised.
