The chemical equation CuO + H2 -> Cu + H2O

  1. Detailed information about the reaction CuO + H2 -> Cu + H2O:

    • This is a chemical reaction between copper (II) oxide (CuO) and hydrogen (H2) to produce copper (Cu) and water (H2O). In this reaction, copper is reduced from an oxidation state of +2 to 0, while the amount of hydrogen is oxidized from an oxidation state of 0 to +1.

  2. Reaction conditions:

    • The reaction occurs at high temperatures, usually above 300 degrees Celsius.

  3. Reaction process:

    • At high temperatures, when copper (II) oxide (CuO) is placed in a hydrogen (H2) environment, hydrogen molecules will react with the copper (II) oxide, reducing the oxygen from the copper and forming pure copper and water.

  4. Phenomena that occur:

    • The phenomenon that occurs during the reaction is the change in color of the solid from the black of CuO to the red of metallic copper. Copper usually has a characteristic red color. The reaction is also accompanied by heat emission.
