Question

why aluminium cannot be obtained by reducing alumina with carbon?

Answer 1

Hey dude!!!

here is ur ans...

The metal oxide loses oxygen, and is therefore reduced. Thecarbon gains oxygen, and is therefore oxidised. The source of carbon for this reduction is coke, obtained by heating coalin the absence of oxygen. ... Some metals, such asaluminium, are so reactive that their oxides cannot be reducedby carbon.
