The reduction of copper oxide RSC Education

The formula of red copper(I) oxide can be determined by reduction with hydrogen in exactly the same way as for copper(II) oxide. The colour change is less clear-cut, but the powder glows showing that reduction is taking place. Oxides of lead can be reduced by this method using hydrogen, as can other metal oxides. Safety . Wear eye protection.

Reduction of Copper Oxide (solutions, examples,

In this activity, copper oxide is reduced by hydrogen to copper. 2CuO + H 2 → 2Cu + H 2 O

Reduction of copper(II) oxide by hydrogen Resource

Reduction of copper(II) oxide by hydrogen. No comments. Determine the formula of copper(II) oxide by reducing it using hydrogen or methane. Natural gas (mainly methane) can also be used as a reducing agent, but the reaction is much slower. Downloads.

2021-2-11  The reduction of CuO with hydrogen has been studied with a temperature programmed reduction technique. According to a proposed reduction mechanism, the reduction was initiated with a interaction between hydrogen and active sites of copper oxide, the rate of the reduction was limited by the diffusion of water from the crystalline. The activation energy of this diffusion is found to be 13Kcal

Finding the formula of copper(II) oxide Experiment

In this experiment, students heat copper(II) oxide in a glass tube while passing methane over it, reducing the copper(II) oxide to copper. If they weigh the reactants and products carefully, students can then deduce the formula of the copper oxide. This can also be used simply as an example of reduction.
