The above chemical equation describes the reaction between copper(I) oxide (Cu2O) and hydrogen (H2) to produce copper (Cu) and water (H2O).
- Reaction conditions:
This reaction usually occurs at high temperatures.
- Reaction process:
- It starts when copper(I) oxide (a red solid) is introduced into a hydrogen environment, usually by heating it.
- Copper(I) oxide reacts with hydrogen, releasing oxygen atoms, turning into water and releasing pure copper.
- Observed phenomena:
- When the reaction begins, the red solid of copper(I) oxide gradually disappears.
- The pure copper produced has a characteristic reddish-orange color.
- If the reaction is conducted in a sealed container, you can notice an increase in pressure due to the formation of water.
- If the reaction is carried out with a large amount of compound, you may see steam being produced. It will escape if the reaction is conducted at high temperatures and is not sealed.
