Reduction of Copper Oxide Tube. Duration : 1.07 Mins.
Reduction of Copper Oxide Black copper oxide and black carbon powder are mixed together and heated up. The gas evolved is passed into a solution of calcium hydroxide (lime water), a white precipitate of calcium carbonate is formed as the gas passes through the lime water. This shows that carbon dioxide is being produced. As the mixture is heated, the copper oxide is reduced to red copper by the carbon. After the mixture is cooled, you can now see it is red-brown due to the copper produced by the reduction. Video from: www.chemtopics.com
