When electric current is passed through molten aluminium oxide the following reaction takes place:



Name the type of reaction. To what use such reactions are made in Industry?


This is a decomposition reaction. In decomposition reaction a single reactant breaks down to give simpler product.
2Al2O3         electricity        4Al + 3O2

Such reactions are used to extract metals from their naturally occurring compounds like oxides or chlorides.
