Reduction of Copper Oxide

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.

CuO

[HerrPingui]

Your point is?

[mewrox99]

At school I reduced copper (ii) oxide with H2 Gas

[arandumLloser]

ok bill nye what does it do



[Greejal]

What is the method?



[g3ov4n12]

It produce very impure copper powder. Best way is 2NH3+3CuO->N2+3Cu+3H2O.

@MsKillah17

2CuO + C → CO2  + 2Cu↓

[MsKillah17]

What is the formula?

What the formula?

OILRIG- oxidation is loss of electrons, reduction is gain of electrons =]

[killernat]

its so much more fun to do these in labs verse watching a video about it
