Hydrogen Reducing Copper Oxide

H2 + CuO → Cu + H2O

Visão geral

Hydrogen gas reduces copper(II) oxide to metallic copper and water when heated. The black copper oxide powder turns to reddish-brown copper metal, and water droplets condense on cooler parts of the apparatus. This is a standard experiment demonstrating reduction with hydrogen.

Exemplo do cotidiano

Hydrogen reduction of metal oxides is the principle behind reducing atmospheres used in brazing and soldering to prevent oxidation.

Importância industrial

A redução com hidrogénio é utilizada na produção de cobre puro para eletrónica e na redução direta de óxidos metálicos na metalurgia. O processo é também relevante para a produção de pós metálicos de elevada pureza em metalurgia do pó.
