Hydrogen Reducing Copper Oxide

H2 + CuO → Cu + H2O

概述

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.
